rcwilbur Posted December 13, 2018 Report Share Posted December 13, 2018 I have a new to me '78 M20J. During the pre-buy the mechanic pointed out that there was a foam filler piece missing between the duct and the oil cooler on one side. The oil temps are fine, but I would like to replace the filler piece. I looked in the Mooney Parts Manual and it is listed as part no. 620017-000 but when I google that number the only hit is Lasar and they are out. My question is whether there is generic foam tape that is suitable for this application and if so the brand/type. It seems that whatever is used should be suitable for a higher temp environment and that just a generic brand from Home Depot is not appropriate. Thanks. Appreciate any help or advice.

orionflt Posted December 13, 2018 Report Share Posted December 13, 2018 you can use a generic piece of felt or foam that can handle the heat of the area, or seal the gap with some high temp RTV Brian Quote Link to comment Share on other sites More sharing options...

Kenfen Posted April 26, 2023 Report Share Posted April 26, 2023 I know this is an old thread, but I used McMaster Part number 1488N639, as a replacement seal for the Oil Cooler of a 1984 Mooney M20J, PN 620017-000: https://www.mcmaster.com/1488n639/ I could only buy in lengths of 10 feet. I can send anyone a length if they need it. Ken. 1 Quote Link to comment Share on other sites More sharing options...
N201MKTurbo Posted April 26, 2023 Report Share Posted April 26, 2023 I just used weather strip from HD. Which is holding up well, but that looks better. I will take some from your stash. I will PM you. Quote Link to comment Share on other sites More sharing options...
