steam valve washers (rubber composition disks)
Tim Gardner
Member Posts: 183
I'm trying to locate new washers for some old steam valves. I am told that regular rubber won't withstand steam, so they must be made of a specially formulated type of composition rubber.
New American valves are only $20 each, but I much prefer the original 1925 ones with the wood handles and finer details. I emailed the company to ask where I could order the composition disks but have not heard back yet.
The plumbing supply house and the replacement parts store and the best hardward store in my area does not have anything.
I need something to fit in a 1 1/4 angle valve. The one in there now is about 1 1/2 outer diameter with a 3/8 inch hole in the middle, but the metal part which closes on it is 1 1/4 diameter, so the inner hole could be a bit bigger and the outer size does not need to be a full 1 1/2.
If I could buy some of the compisition disk material I could cut my own. Anyone have any ideas?

valve rubber
Don't know where you're located but here in Portland we have a company called Portland Rubber that sells hoses, belts, sheet rubber and almost anything made of rubber. Also have acompany that sells and makes gaskets and seals of every type imaginable. Check your local area for this kind of supplier and you may find what you're looking for. We use to repack valves in the paper mill here with specialty rubber gasker materials purchased from this supplier. Good luck.

Try a good auto/truck parts store, they will have sheets 12\"x12\"
they look like flat black marble about 1/8" thick and cut easy. Also I think grangers has it too. Hope this helps John@Reliable0 -
Are you sure this can withstand steam? The parts store guys say the regular stuff can not.
Thanks,

Rubber sheet
Check out Mcmaster-Carr. They stock just about every type of rubber known to man. They also have a selector which shows the characteristics of each type of rubber and the recommended temperature range.

Viton might be best for the application, as it is good to 400F, but is a little pricey. Used for high temperature valve seals in automotive engines.

EPDM rubber
EPDM rubber is what's generally used for steam service. Second the endorsement of McMaster-Carr0
