Loctite Lubricants Sealants Adhesives - LT37467

  • Gasket Maker
  • Sealant
  • 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.

Its has held up, no leaks. No problems



by:

This went on without a problem on a 2022 Subaru Outback thankfully providing the built-in wiring harness that is located under the right side rear trim piece, I did not need to remove. I used 3M Dual Lock in case the control unit needs to be easily moved in the future. Using this for a OneUp Bike Rack and their license plate and LED light bar.



by:

Originally ordered to close extra holes in a Yakima Rocket Box that required new hardware. Does the job.

etrailer provides excellent information, support and customer service. I wish every online vendor was close.



by:

Worked as expected.



by:

Refer to prior review



by:

Great product and the usual excellent service from etrailer !!!!



by:

The carrier performs just as it was designed. Putting the rubber sleeves on was difficult and the sealer has already pealed of . Before I use it again I will put silicone caulk on the joints



by:

i used this product when I put together my cargo carrier. I put it on the bolts before I screwed on the nuts for added insurance to keep the carrier nice and solid.



by:

Bearing buddy is still on the trailer and the wheel is still turning.



by:

works well, be careful on the pressure you apply. I applied too much pressure (i was rushing it) and it went out the back end... complete user error but be warned.

Good product.



by:

Did not work to seal up my failing brake light gasket. Also very smelly in spite of being labeled as "low odor"



by:

Saw it used in the video to install tail lights. Worked great and sealed the light assembly. Easy to use.



by:

Seems to be doing it's job just fine, and helped with the installation of the rack



by:

I used this to seal the hole I had to drill in my car when installing my hitch to keep water and exhaust out of the cabin, it dried quickly and created a good seal to keep stuff out



by:

This is the perfect RTV for way covers on CNC machines. They seal the coolant out and yet you can get the covers back off without damaging them.

  • Can You Bypass Solera Exterior Smart Awning Touch Pad
    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. These arms would use your existing fabric...

    When you install the 4-Way, like the preferred T-One Vehicle Wiring Harness # 118449 over the Hopkins # HM11141845, on your 2011 Toyota Highlander you want to look for a plug at the bottom of your cargo area. 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...

  • Do the Inno Memory Mount Clamps fit an Older Inno LowDown Cruiser
    Hey Andrew, unfortunately the Memory Mount Clamps for Inno Rooftop Cargo Boxes # INBRP9 are not going to work with your older Inno LowDown Cruiser. Your only option to retro fit it is to drill holes in your cargo box and use the U-bolt kit # TH05603. You'd also need sealant # LT37467 to seal your old holes.

  • Roof Vent with 110V-AC Powered Fan for 6 x 12-Foot Diamond Cargo Trailer
    Most square trailer roof vents are a common size, 14 x 14, and they require a roof opening of 14-1/4 x 14-1/4-inches. If your vent measures this approximate size then you can safely presume you have one of these standard-size roof vents. We do offer a 110V-AC powered fan in this size that is shown on the linked page, part # V2128SP-01 from Ventline. This vent features a manual-lift lid, on/off switch, insect screen and it also includes an internal trim piece (the garnish) for a clean installed...

  • Installing Buyers Products Utility Storage Box
    The Buyers Products Utility Storage Box - Black - 44" x 19" x 17-1/4" # 3371712240 does not come with any installation hardware. Because of the style of box you can drill through the bottom and use zinc plated bolts, and locknuts or you can use U-bolts. The length and size can vary as it will be dependent on your specific application. For example, the Replacement Cutting Edge Carriage Bolts and Nuts for Boss Snowplow - 5/8" x 2" - Qty 10 # 3371301064 could work well. I recommend using...

    Hey Roberto, If your ground is showing power then the contacts in the backside of the 6-pole socket from the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267 have likely corroded and are touching. Once the wires are in we usually fill the rubber boot up with some RTV gasket maker # LT37467 to prevent corrosion. You'll want to take the 6-pole socket apart and likely replace it with # RM-910030-7. You may also need to trim off a bit of the wiring if it's corroded or brittle...

  • Mounting Buyers Products Utility Storage Box to Cargo Carrier
    If you want to secure your # 3371712250 to your hitch mounted cargo carrier my first recommendation would be to use straps. If you're looking for a more permanent solution then drilling holes and using bolts and washers would be enough I'm sure without installing a plate in the bottom of the box to secure it. However, if you are planning to drill holes I would recommend sealing the holes with something like the # LT37467. You wouldn't want to end up with water inside if you're driving...

  • How to Mount 7 Way to 2019 Subaru Outback With Hidden Cross Tube Hitch
    I understand the frustration, manufacturers are making hitches more hidden and sleek. It's nice having the cross bar hidden, but it does make it challenging to mount wiring because that's the traditional spot. You can route the 4 pole wire out to the bumper through a grommet that is under the spare tire. I have done that many times to get the wires out towards the hitch, you'll just want to make sure the wire is protected and to seal the grommet up with some silicone # LT37467. You can...

    I would be happy to assist you in choosing the best wiring kit for your 2022 Kia Seltos! The Curt Trailer Hitch # C65FR that you have is an excellent hitch choice, but when it comes to wiring I recommend going with the Curt # C89KR over the Tekonsha wiring simply because Curt electric products tend to last longer and require less troubleshooting than Tekonsha electrical products do. In addition to this wiring I also recommend picking up the mounting brackets # 18144 and # C57202 so...

    We do not carry the grommet in question for your 2008 Toyota Highlander, but you may still be able to route the wiring under the vehicle and to the hitch using an existing grommet near the connection point for the wiring harness at the rear of the Highlander. If there is a near by grommet that allows access to the outside of the vehicle, what you can do is to cut a small slit in it, pass the 4-Way through, and pull it over to the hitch.

  • Is There A Mounting Hardware Kit For UWS Truck Bed Tool Chests
    The UWS Truck Bed Chest # UWS01047 doesn't come with any mounting hardware and doesn't actually have any holes predrilled into it for mounting so it would be a custom job to mount it. That being said you could just drill through the bottom of the box and through the bed of your truck and use some larger washers and bolts to mount it, like you stated. I do recommend using some gasket maker # LT37467 over the bolts so you don't run the risk of water getting inside of your tool box though.

  • Should the Power Wire for the Curt # C56387 be routed Inside or Outside on a 2018 Chevy Malibu
    Typically the power wire for a wiring harness like the T-Connector # C56387 that you are installing on your 2018 Chevrolet Malibu is routed outside and under the vehicle. If you can locate a grommet like part # A11GB at the rear of your vehicle you can then route the wire outside without drilling through your Malibu. Be sure to seal it back up with a gasket maker like part # LT37467. Once outside we usually try to route the wire through the frame as that will keep it protected pretty well....

  • Why Does Hitch for 2014 Honda CR-V Have Mount for Wiring When it Installs in the Cargo Area
    It does seem rather odd that Draw-Tite # 75742 would construct the hitch with a mount to attach a trailer connector mounting bracket when the trailer connector harnesses for the vehicle are designed to be installed so that the trailer connector is stored in the vehicle when its not being used to protect it from damage and corrosion. If you can locate a grommet in the floor of the cargo area that would allow you to pass the 4 pole connector outside the vehicle, you could certainly do so....
