Butyl tape is an essential tool for weatherproofing marine and RV components. This sturdy material creates a long-lasting, weatherproof gasket to fill gaps between your RV's outer hull and the mounting points for vents, windows, and doors.


  • Butyl tape functions as a gasket for a weatherproof seal when mounting RV or marine components
    • Sticks to the underside of mounting brackets and installation points before pressing into place on your RV or boat
    • Provides greater protection from the elements than using sealant alone
    • Prevents the intrusion of moisture into nail or screw holes
  • Adhesive works on most nonporous materials including roofing membranes and metal
    • Designed for use with LaSalle Bristol XTRM RV roof membranes
    • Won't crack, harden, or shrink
  • Easy to use - press tape firmly to first surface, remove backing, and then press onto second surface for an even seal
    • Trim grade tape means you can easily scrape away excess with a putty knife
    • Applies best to clean and dry surfaces
  • Gray color
  • Made in the USA


  • Quantity: 1 roll
  • Dimensions: 30' long x 1-1/2" wide x 1/16" deep

Butyl tape is used primarily as a gasket for preventing moisture from leaking into your RV around cutouts in the hull for vents, doors, windows, and wiring outlets. Butyl tape is widely used by RV manufacturers because of its high performance and durability. It does not dry out and crack over time, and its strong adhesive quality means it sticks and stays in place on smooth surfaces.

Butyl tape is most often used in conjunction with sealants to create the highest level of weatherproofing to prevent leaks and ongoing damage. It's ideal for use in areas where fixtures need to be drilled, nailed or bolted into place. The rubbery material keeps those openings sealed and free from water damage. While this is great for those who do their own repairs and upgrades, butyl tape is also good to have on hand to make temporary repairs. The tacky material can plug up any problem areas and hold strong, so you don't have to cut your trip short.

Received the 7.5 slide topper in record time. The person I talked to when ordering was very helpful and very friendly. Installed it today on my 2019 Jayco Redhawk 22 foot motorhome. Installation went without any problems. The hardest part was the last step of putting the 1/4" screws in the top rail. Had to put them in the bottom of the rail instead of the top. Not sure if they went through the bead of the topper. Is that a important step. Would appreciate someone getting back to me on that.


Excellent quality.


I haven't installed the roof yet, but most of the products have arrived.. customer service was excellent, the items came quickly and as ordered. I will do a final review when this phase of the remodel is completed.


been over a year and still holding the same as day 1. used it to seal the maxair fan


Tape works great


The products arrived in perfect shape!

husband grabbed them and ran out the door with them. He now has 3 new slide toppers in place on the fifth wheel, all sealed up weather tight!

Thank you for the video's showing how to install as well as the products necessary for installation!


Great quality product! Had to redo my 1995 fifthwheel roof and used this for roof vents as well as the side drip rails. Works great, quite sticky too.


Easy to use, paper came off fine, worked great for replacing a skylight, I used a double thickness between skylight and roof membrane of trailer, no issues at all. also used some for replacing outdoor speakers on same Rv. Great product.


This tape is extra wide and perfect for the larger trim molding I am using to seal up my slide out. Much better than trying to double up the usual tape. It works very good and is easy to habdle.


Appears to work as intended. Just wish I didn't have to buy such a big roll.


The 1.5" width made it easier for the rail installation I was doing for a slide out cover. Works well and what install video showed as 2 strips of 1" with trimming to do


product came as describe and quickly. no issue with putting it on. keeping product in the fridge is very good advice. still have part of a roll left and it is the same as when I bought it a year ago. excellent place to purchase all trailer needs , will buy here again.


3rd time is a charm! After ordering the same product elsewhere twice, a trailer came through for us! Exactly what we were needing to complete our project.


The original delivery went to the wrong address, but replacements were quickly sent I received the packages.


Everything that I ordered came in good shape. Thanks for the prompt action on the order. A pleasure working with your company again.


Easy application wider than expected but easy to trim after application.


Good Quality fast and easy service


This tape is amust for every RV'er. It's the best way to help seal up leaks when making on the road repairs etc. I don't leave home without it. God bless.


It took me a bit to find this my husband kept telling me he needed the wide stuff. i finally found this it just what he wanted


Applied easily and the paper pulled off cleanly. Great seal.

  • Your camper shell will be fine using the 45-Degree T-Style Hook and Keeper Door Holder for Enclosed Trailer - 3-3/4" - Stainless Steel Item # 37211765 to hold the door open, even in the wind. I recommend using some Butyl Tape Item # 344270341411-1 on the brackets to ensure a water tight seal in the screw holes and will also add some extra grip strength to your brackets.

  • Assist Handle # 37248325 Sealer Installation Tips

  • Will Screw-In Snaps for Adco Storage Skirt Affect Integrity of Trailer
    The small screw-in snaps for the Adco Storage Skirt # 290-3501 will not affect the integrity of your trailer simply because they're really just going to mount to the exterior panel on the trailer. We have not had any feedback from customers regarding damage or leaking as a result of the screws but if this is something you're concerned with I recommend simply using some butyl tape like # 344270341411-1 to seal everything up.

  • Butyl Tape To Seal Trailer Roof Panel Joint
    The LaSalle Bristol XTRM Butyl Tape part # 344270341411-1 can definitely be used to seal the joint on the roof your cargo trailer. Butyl tape is used to seal off many roof accessories like trailer vents and fans. Since the butyl tape is pre-formed it is easier to install and get a water tight precise seal compared to some of the liquid sealants that can be more difficult to maneuver. The adhesive on the tape forms a bond with the surface that improves over time. This particular butyl tape...

  • Is Butyl Tape Recommended When Installing Fan-Tastic Vent Roof Vent FV807350?
    Butyl tape like # 344270341411-1 is recommended for making sure you get a leak free install of your new Fan-Tastic Vent Roof Vent # FV807350, but it can be done with just the lap sealant you have. You will just need to make sure you apply it liberally between the roof and vent, making sure to get some in the holes so water does not get in past the screws. I included a video of the # FV807350 for you to take a look at.

    Since the bumper on the Low-Profile Bumper Door Holder for RV or Enclosed Trailer # 37210665 is going to pop into the holder and require you to pull the two apart using other means to hold them to your glass door will most likely not be enough to hold it. Instead I recommend using the T-Style Hook and Keeper Door Holder for RV or Enclosed Trailer # 37210324 so you can use some tape like # 344270341411-1, or any other brand you trust. This style door holder won't require you to pull the...

  • Slide Out Toppers For 153" and 79" Slide Outs
    For your 79" slide out I recommend the Solera RV Slide-Out Awning - 6'7" Wide - 48" Projection - Black Item # LCV000168105. For the 153" slide out I recommend the Solera RV Slide-Out Awning - 13'1" Wide - 48" Projection - Black Item # LCV000168109. I recommend using butyl tape item # Item # 344270341411-1 on the brackets to get a water tight seal on your screws.

The Self-Tapping Screw - 1/4" -14 x 3/4" # FA1131822 is the recommended screw for this and you will also need LaSalle Bristol XTRM Butyl Tape - 45' L x 1-1/2" W # 344270341411-1. I attached a demonstration video for you.

  • Recommended Solera Powered Awning Arms For A 2008 Komfort Trailblazer Travel Trailer
    To replace your current awning arms with Solera Powered Awning Arms you'll need part # LC759517. These arms can splice to the wiring you already have in place for your old Dometic awning. While Solera fabric/roller assemblies are compatible with other brands, the arms are only compatible with Solera branded assemblies. These arms are 69" in length so they'll fit nicely in place of your old arms. I do recommend using some butyl tape # 344270341411-1 on the brackets during installation...

  • Recommended Slide-Out Awning for 2015 Sanibel 5th Wheel Trailer
    You are correct that the Solera 14' Slider (Slide-Topper) in Black w/ Black Hardware # LCV000168110 or white # LCV000163301 is the correct fit for the measurements you gave. This fits measurements from flange to flange of 158 to 163-3/4 inches. This comes with all the hardware needed to install except for the Butyl tape like # 344270341411-1 or silicone sealant like # 344270341437-1. I've attached some videos of the installation to assist.

If your trailer does not have a rail installed you can use the Solera Awning Rail Extrusion # LC715217 and install it with some butyl tape # 344270341411-1 and self-tapping screws.

It does not come with the rail extrusion like # LC715217 to mount the awning fabric to the side of the RV. If you are installing a new rail extrusion, the LaSalle Bristol XTRM Butyl Tape - 45' L x 1-1/2" W - Qty 1 # 344270341411-1 and Self-Tapping Screw - 1/4" -14 x 3/4" Long - Zinc # FA1131822 are my recommendation.

You would additionally need 3 Solera # LC715216 eight foot awning rails. You will need LaSalle Briston # 344270341411-1 Butyl Tape for the rail installation.
