I was going to buy some of these off mcmaster....
9307K27
Military Specification Buna-N Rubber Grommet MS 35489 No.43, AN 931 No.A8-13, 1/2" ID, 1-1/16" OD
and then I saw a post that said no buna rubber. Does it just have a short life, or does it actually break down in the methanol? I need some grommets 1/2" in internal diameter in 1/8" and 1/4". Anyone know where I can get some that are safe for my app?
This is for the windshield wiper tank. I have the bulkhead, but I don't know how to get the backside part of it screwed on since I have an odd shaped WW container that's kinda of got a small neck. It's for a 92 vette.
Instead I was thinking of using a .56" diameter tubular fitting pushed through a 1/2" diameter grommet.
Any ideas on what i can do? The other material choice that they offer is silicone, which appears to be more heat resistant, but I'm not sure of the chemical resistance.
