installed on the copilots door of my 1961 C182D. It was a very tight fit at first after three days with the doors closed and latched it fit great with no leaks.

The seals will be initially too thick. You need to let the doors sit CLOSED for 48 hours or more if its cold. They will compress and form a custom tight seal.

Its a good seal. When I ordered it, I thought it was enough to cover both doors. It does not, only one door for an expensive price.

This material is much too thick for the 172 door. Weve had it installed for almost two years and all it has done is cause undue stress on the hinges and latch mechanism which has lead to a broken door latch linkage. Go to the hardware store and purchase something cheaper that will also fit better.

I attempted to install these door seals on a Cessna 152. They were much too thick and the cabin door would not close. I removed the seals and installed the Cessna door seals (PN R581573). The Cessna seal fit well. I wasted more than eight hours installing and removing and than reinstalling the Cessna seals. The most time consuming part was removing the adhesive. I gave the product one star because the seal was well made.

The door seals are very high quality but do not fit our 1967 T-41B (R172E) Our doors fit perfectly but the seals are simply to thick and too wide to allow the doors to close. We followed the directions carefully and the seals were correctly oriented. We now have a big mess in trying to remove the seals on the one door we did.

Q: C-120 entry door seal. Is that the same as the OEM stuff or is it a new design?

Per the suppier: Our C1401 seal is a new design.

Q: I wish to replace both left and right door seals. Do I need to order two of them or does it come as a kit with enough material to do both doors? Also, does it come with the adhesive too? If not, what adhesive and how much is recommended for a cessna 170?

Yes, you would have to order two of them if you wish to replace the left and right door seals. They are sold as each (per door).
