tstockma Posted September 13, 2021 Share Posted September 13, 2021 (edited) HI all, the exit hatch on my '86 New Horizons has a hollow, round seal that is mounted above the screen, pressed up again the actual plastic cover when it's tightened down. Old & disintegrated along part of the edge. I have a couple inches of a different size as a sample, but it's a tad smaller & the "mounting foot" of the new has no "riser", the old has a short "riser" molded into it. The new is approx 1/4" inside diameter, the old looks about 3/8". My RV parts store doesn't have the 3/8 size. Anyone have a good source? Amazon fails me here... And is there specific name for this style seal? Thanks for the great knowledge & help here!
