Good gasket source?

Building a propane locker. Reg’s say it must be “sealed” at the top.

The last time I purchased off-the-shelf self-adhesive gasket material from Home Depot for an ice box lid, it shrunk badly, leaving large 1/4” gaps at each mitered corner. So not going that route again…

Anyone have a source for good quality self-adhesive gasket material? Also, is it possible to source something that is so flexible that I can just make radiused corners, instead of cutting 4 separate strips then mitering each corner?

Re: Good gasket source?

Leo Sampson on Tally Ho (https://sampsonboat.co.uk) seems to have used surgical tubing set into a rabbet around the lid of his electrical panel to keep water out. He generally knows what he's doing. Would foam self-adhesive gasket material (weatherstipping?) actually seal gas that well in any case? Try looking at McMaster Carr for gasket tape or other options.

Re: Good gasket source?

How good of a seal is required, considering that there is a big drain at the bottom? Can't build up any pressure to speak of...

Just trying to understand what the aim is!

Me too! ?
It seems for air to flow out the bottom drain you NEED a leak at the top...? I dont remember seeing a factory boat with a sealed lid, although I cant say I've looked at a ton of them. Is this new?

Re: Good gasket source?

5 surveys over 20 years never mentioned a seal on my propane locker. What was important to the surveyors was a warning plaque that says this is LPG, don't hook up LNG.
