Can Butyl Tape Be Used When Installing Ventline Roof Vent On Flat Aluminum Trailer Roof

Question

Question:

Im installing this vent on a 7x16 foot Charmac cargo trailer with a seamless, flat, aluminum roof. Is it necessary or helpful to use a layer of butyl putty tape between the galvanized vent flange and the aluminum roof? I plan to use urethane sealant on top of the flange, and over the screws in any case. Thanks.

It sounds like you have a good idea of what to do when installing your Ventline Roof Vent, part # V2092SP-29. You sure can use the butyl tape that comes in the kit like part # CAM25013 as you mentioned when completing the installation. The butyl tape is pliable and should provide a nice surface for the vent. You will want to make sure the surface is clean and free of dirt or moisture when using any sealer or tape.

Just to make sure everything is sealed really well you can use a sealer along with the tape to make sure there are no air leaks or chances for moisture to creep in. I recommend the Loctite RTV Sealer, part # LT37467 for the job. Sealing the screws when installing them will help provide a nice barrier for you.

We have the replacement valve for Dometic Pedal RV Toilets with the part #DOM93FR which sounds like what you are looking for. Since you said you have a 310 series we know this is a fit too as that is one of the listed toilets it fits.

Realistically it is best to stick with a Dometic replacement thermostat for your Dometic setup. The #DMC79FR is the correct replacement for your 3316410.012. It may be possible to use a universal thermostat like the #CAM09221 you looked at but this…

Hey Cindy, the PowerMax Membrane Plus RV Roof Replacement Kit w/ Rolled PVC Membrane #PM78VR is rolled. So it ships on a roll and is not folded.

Hey Dustin, the replacement lid you ordered a few years ago was the part #BVD0449-A01. I know it sucks yours fell apart but these aren't really designed to withstand a hail storm so I am not shocked yours broke apart. Would you prefer metal lid…
