Canopy seal

[ccsmith51]

Does anyone know of an expanding seal that goes between the canopy skirt and the fuselage skin?

I recall reading somewhere about a seal material that conforms to an uneven gap. I believe that you put the seal on, close the canopy, let it sit for some amount of time to set, then the seal maintains that shape after it sets.

Does this ring a bell with anyone?

Thanks.

This is what I used on my -7. Applied to the canopy frame and it seals beautiful along the entire length. https://www.mcmaster.com/products/d...-foam-rubber-push-on-seals-with-bulb-on-side/

I can’t remember the exact size, but it’s one of these

George, did you apply this just on the sides, or also under the front edge?

MacMaster Carr part # 1120A111 is the seal I ordered. Just used on the sides for my tipper. When you originally build your canopy you space under the rails 1/8". This seal compressed is slightly more than that so a small adjustment had to be made with the latch fingers. I ordered it in a 10' length so I would have some extra for errors in installing.

Same as alphacharliebravo, just along the sides. The front edge weather stripping is a different adhesive based type.

I haven’t looked closely at the nuances of a RV canopy frame, but my current Lancair (tip up canopy) has an inflatable canopy seal. Quantum leap in sealing from my previous Lancair with a plain seal.

Obviously, a level of complexity and work above sticking on some weatherstripping, but I’m thrilled with it and it’s been problem free to date. i’m not sure if the RV design lends itself at all to this (I haven’t seen one with it), but FWIW.
