Hey man I'm in the process of cutting my own washers out of a sheet of 3/16" thick Neoprene at 50A durometer that I ordered. It's really not turning out the way I hoped though and now I'm stressing about constructing a functioning system that doesn't leak everywhere. Do you think I can have success manually cutting these things out? I know that my inner diameter definitely can't be too big and my outer can't be too small so I'm kind of using that as a guide. They don't look awful but not that good. Short of having them manufactured, you think my best bet will be to just take my time cutting these to as close to the proper dimensions as possible? I called that store in my area which had part #420 at one point but no luck there.
This is a quote taken from somewhere in this thread:

Its reliantrubberco.com. They respond fast and answer the phone when you call.
Overall as a customer id give them a 10/10 no problems whatsoever and price is fantastic.
Id ask about 50 durometer though. I forgot to mention that so i got 60s and they are a little on the hard side. I really had to tighten the nuts with channel locks to prevent leaks. 60s did work fine though after being tightened.
I don't know how you are going to cut your own washers. I would have never gone that route. Try the company that this guy talks about and see if they have those washers. Let us know.
