Are these still made? I'm trying to find the seal kits for the manifold. Regular o-Rings are to big.
These had 4 valves and then the end caps. Say model 793 which doesn't come up in google.
I hate to replace them all if I can repair or rebuilt this one.

Not sure what you mean by regular O rings are too big, you can get them in almost any size and cross section, including metric sizes.

You might check with your local bearing house or pneumatic supply also.

United States | Mac Valves Maybe one of the listed distributors could help.

Try The O-Ring Store, We make getting O-Rings easy!

They sell every size of O-ring you could dream about, and they sell them in SMALL quantities at very reasonable prices (unlike a few well-known shops).
There is zero chance they will not have the sizes you need.

If you are unable to find what you need, O'rings, we offer entire replacement of the valve. They still make these Mac valves and we stock them.
