Loctite Lubricants Sealants Adhesives - LT37467

  • Sealant
  • Gasket Maker
  • 2.7 oz
  • Loctite

This black silicone gasket maker forms a high-quality gasket that seals the space between matched parts to prevent leakage of automotive fluids and gases. It meets manufacturers' specifications for original equipment.


Features:

  • Seals joined parts in automotive systems - prevents leakage of antifreeze, air, oil and transmission fluid
  • Meets manufacturers' warranty requirements
  • Resists oil better than other silicone gasket makers
  • Won't interfere with sensors
  • Won't corrode
  • Resists vibration
  • Made in the USA


Specs:

  • Quantity: 2.7-fl oz tube (80 mL)
  • Tack-free cure (time required to dry past tacky state): 30 minutes
  • Full cure (time required to reach full set): 24 hours
  • Temperature range (endurance limits of the gasket maker): -75 F to 625 F
  • Ideal gap-filling capacity (gap sizes in which gasket maker performs best): 0.001" to 0.125"
  • Maximum gap-filling capacity (maximum gap size between joined parts): 0.240"


Applications: Valve covers, oil pans, timing covers, water pumps and thermostat housings



Applied as a gel to just one surface of the parts to be joined, silicone gasket maker forms a seal between them, keeping out contaminants. Silicone gasket maker resists oil and shop fluids, vibration, heat, and flexing of parts, replacing many conventional gaskets. Parts joined by this silicone gasket maker can easily be removed. The old gasket material comes off effortlessly, simplifying future disassembly and reassembly.


Because of their ability to flex and compress, silicone gasket makers work better than other kinds of gasket makers when the parts to be joined are made of different materials, which have different rates of expansion and contraction when temperatures change. They also work better than other types of gasket makers on stamped metal parts that can flex and in situations where clearances can be large.

Excellent product; can't find on store shelves. Pricing from this supplier is great.

Exactly what I needed for the job I was doing.



by:

Great product! Great service!!



by:

No problem !



by:

We use this product for creating gaskets where needed, and until now had no reasonably-priced supplier. We really appreciate your pricing and service. We had our last order of six units in three days!



by:

The product was shipped as promised. Product worked fine and was of satisfactory quality



by:

Worked and fit just like described, good deal.



by:

smooth transaction

I used this product to repair a leaking auger gearbox on my snowblower. It was critical that when repairs were completed the two part gear case be sealed completely. The directions were simple/straightforward and the product was easily applied. I used the snowblower all winter and the gearbox seal was perfect.



by:

Thank you for fixing it promptly, I appreciate It. I have received the replacement.



by:

I received my product very quickly and in excellent condition! Every time I have ordered from E-Trailer, I have been extremely satisfied!



by:

Only bad thing I have to say about it is don't know if it was shipping or a factory defect but followed directions on package and cut nozzle to desired size and started squeezing it on my transaxle and the locktite started coming out of the side of the tube. So I'm out of half the tube.



by:

Great adhesive quality upon applying , not to fast drying so u can move items around to line up holes like I was for trailer vents on side in race trailer . Haven’t used the trailer yet since thr rainy season to see if weather affects the bond but can tell u the grip is fantastic as we scrapped one of the vents accidentally against a building roof overhang and it creased the metal vent but did not displace, pull or unseal the vent! I would use this to mount anything to thr exterior of my trailer without worry!



by:

I used this to seal my hitch install. Ok so I over did it, but the seal Is excellent. One tube is plenty for the 2 holes drilled in the spare tire well. If fact you could do several. It just shy of a tube of toothpaste size to give some perspective.

This item was great for rear sealing the two grommets that had to be cut to install the wiring harness

I assume it's working well. I used it to install the block warmer on my truck. No issues.

Works great.

  • Replacement Mounting Hardware for a Sears Sport 20-SV Cargo Box
    They do not make any specific replacement parts for the Sears Sport 20-SV anymore however, you can certainly make the Replacement Mounting Hardware part # CTC-18PARTS work for you. The holes may not align perfectly but you can always drill new ones and use part # LT37467 to cover the old ones. This is a very popular option for the older Sears cargo boxes like what you have.

  • Universal Monitor Mount for Observation Camera Systems
    Furrion and RVS camera systems use different mounts so the RVS Extendable Monitor Mount # RVS-1419 will not be compatible with your Furrion monitor. But we do offer a couple of universal-type monitor mounts that may be adapted to work with many monitor screens. These are shown on the linked page and include Voyager 4-inch mount # VOSHD4MNT and 6-inch mount # VOSHD6MNT. These are screw-on mounts so if you prefer a suction cup mount have a look at part # PVOS5SCM. If you want to use one...

  • Recommended Roof Rack and Cargo Carrier for 2013 Toyota Corolla
    For your 2013 Toyota Corolla, I recommend the Rhino-Rack Vortex Aero Crossbars # RRVA118B-2, the 2500 Series Legs # RRRLKVA, and the Custom DK Fit Kit # DK152. This is a confirmed fit for your vehicle. I also recommend the metal lock cores # RRVA-LEC4 for when you use the T-channel mounting for accessories that have that mount that fits in the slot on top of your crossbars instead of wrapping around them. Then for your rooftop cargo carrier, I recommend the Thule Force XT Rooftop Cargo...

  • How to Mount Yakima SpaceCase Cargo Box to Factory Crossbars on 2020 Subaru Forester
    I do have a solution for you, however I reached out to my contact at Yakima and he said the Universal MightyMounts # Y03590 aren't compatible with your older SpaceCase Cargo Box. The mounting hardware for the SpaceCase is a bit different and you won't be able to properly attach the MightyMount clamps. Your best route for mounting the SpaceCase to the wider aero-style factory crossbars on your new Forester is to replace its existing hardware with part # 8870098. This kit consists of similar...

  • Recommended Placement and Sealant for Installing Polar Multi-Purpose Ventilator PLR20
    The Polar Multi-Purpose Ventilator # PLR20 has a lever to close the vent when there is risk of heavy rain (please see the linked photo) but the vent will block most water since it also has down-facing louvers on the outside. The lever lets you choose how much airflow you want. Using one at each end of the trailer is a good way to provide cross-ventilation and for the most cooling I suggest placing the rear vent up high (so it can expel more hot air from inside the trailer) and the front...

  • Can Swagman Roamer LT Roof Rack be Installed on a Cargo Trailer?
    The Swagman Roamer LT Roof Rack for Pop-Up Campers and Camper Shells - Steel - 7' Long - 150 lbs # S80510 can be safely installed on your cargo trailer. You will simply want to account for the weight capacity of the rack, the trailer components, and the height of the trailer with whatever you add to that rack. It will make it more top heavy the higher the load which will impact cornering and wind or passing vehicle sway. Swagman designed it for pop up trailer use which is much lower...

    The black ModuLite box that comes with the Tekonsha T-One # 118449 for your 2019 Toyota Highlander not only includes the connections needed to activate the trailer light wiring on your vehicle, but it also combines the light functions (like what almost every trailer uses), pulls 12V power directly from the battery so as to not strain your vehicle circuits, and provides protection in the case that your trailer wiring fails. To establish whether or not you have the tow package just look for...

  • Replacement Locks and Keys for Thule Ski Box with Key Broken Off Inside Lock Cylinder
    With a key broken off inside the lock, your only option is to drill out the lock and replace the core. For the replacement cores and keys for the matching set, I recommend the Thule One-Key System Lock Cylinders - Qty 2 # TH450200. With the key broken inside the lock, the master key won't work, so carefully drilling or calling a locksmith to drill for you are the only options. You may be able to drill into the key directly enough to get a bite so you can pull the broken key out and...

    Hey Brian! I'll start out by confirming that both the Draw-Tite item # DT94YR and our etrailer item # e25TR hitches fit the 2024 Subaru Outback Wilderness. The hitch pin hole sits 2" back from the edge of the bumper on the Draw-Tite item # DT94YR and 2-1/2" back on the etrailer item # e25TR. The fish wire tool is included with the etrailer item # e25TR hitch.

  • Recommended Converter to Separate Brake Light for 2013 Silverado 1500 for European Requirements
    The Curt Vehicle to Vehicle Tail Light Converter # C56196 is what you need to separate your brake light signal from your turn signal. This converter will take your combined turn and brake signal and isolate them so you will have left turn, right turn, and stop. This will help you to isolate the brake light so that you can meet the European standards.

  • What is the Diameter of the Crosstube on the Draw-Tite Hitch for a 2018 Dodge Journey
    The inner diameter of the crosstube on the Draw-Tite Max-Frame Trailer Hitch Receiver part # 76225 is 1-1/2". Therefore, a trailer hitch cover designed for a 2" receiver tube opening like the Rubber Hitch Cover part # 22282 will not work for this application. With that being said I am certain you could find something to work for this application with just a bit of modifications. I have attached a sample install video for you as well.

  • Replacement Lock and Mounting Hardware for Karrite Car Top Carrier
    Hi Mona; I wasn't able to find what model Karrite you have with that model number. However, we have had customers in the past replace their mounting hardware with the # TH05603. You can check the distance between your mounting holes to see if these bolts line up. The U-bolt is 4-3/16" wide center to center. In some cases people have drilled new holes and filled the old ones with # LT37467 when there isn't mounting hardware that fits. If you have the number off of the lock core a Thule...

If you slit this open you should be able to feed the 4-Way underneath your vehicle and then seal the plug back up using Gasket Maker # LT37467. Then you just have to plug in the 4-Way to the back of the Hopkins # 37185 adapter and secure it to you hitch receiver using the No-Drill...

We have the Thule # TH09243 which is 4 inches wide and 2 inches deep. We also have the Car Top Cargo # CTC-18PARTS which is about 4 inches wide and 1-5/8 to 2-1/2 inches deep.

  • Are There Replacement U-Bolts For Thule Evolution Cargo Box
    I may have a solution for you, but there is not a U-bolt available from Thule that is 3-1/2" wide by 3" deep. The closest option available is the Replacement U-Bolt for Thule Trail Large and Medium Cargo Baskets # 1500052553 that is 3-1/2" wide and 1-5/8" deep. Depending on the bar type, you could likely make this work; aero style bars would be the best fit since they'll have the lowest height in most cases. If you wanted to do some light modification then you could technically use any...

  • Replacement Mounting Hardware for Thule Cascade XT
    The original mounting hardware for the Thule Cascade XT is no longer available. A good alternative is the Thule Replacement Quick Mount Hardware # TH04997. This fits crossbars up to 1-9/16 tall x 3-3/4-inches wide. If you end up needing to drill new holes in the box any extra holes can be sealed up using silicone sealant # LT37467. Also, if you need extra height while using your box and installing hardware, I use the Rightline Gear Moki Door Step # RL100660.

  • Replacement Locking Hardware for Thule Frontier 668 Rooftop Cargo Box
    I reached out to my contact at Thule and the bars you are seeking are not available as a replacement option. They have discontinued those style locks so you will be forced to improvise or upgrade. If you choose to improvise, I recommend using the Replacement Hardware Kit, # SR05587. If you need to seal extra holes, you can use the Loctite RTV 598 High-Performance Silicone Gasket Maker # LT37467 to keep the box weather tight.

    If I were you and I was having trouble with water damaging the exterior touch pad, I would first take some silicone sealant like part # LT37467 and seal up the arms as best you can at any place water could enter. If this did not work then the only option we'd really be able to offer is a new set of arms, without the exterior controller such as the Solera 12V Electric RV Awning Conversion Kit part # LC434723 for black or part # LC434724 for white.

I ran out to the warehouse and double checked that the outer dimension of the threaded portion matches the 2.33" of your Turbo Lube 48394 cap. You will want to remove the oil from the hub using shop towels and a mild detergent. Let them dry completely before packing them. Bearing Buddy also recommends using a High Performance Silicone Gasket Maker like Loctite's # LT37467 for the installation.

    Your old Yakima RocketBox has mounting holes that are 4-1/2 inches on center, so there isn't a direct fit we carry.

This will fit your Malone Aero bars like # MPG215 on your 2015 Toyota RAV4 as well as the factory bars on your 2008 Honda Pilot. I recommend using the gasket maker # LT37467 to seal the extra holes in your box to prevent water entry at the unused locations.
