The "real" O-rings are Viton. That's the same as the space shuttle. Hmmm.

I took my original O rings to an automotive shop and found the correct size.
Now the bad news.
They lasted only a couple dozen flights.
I believe the hardware store variety is not of sufficient quality for
reasonable longevity.
I have just ordered the "real thing" from Lance at Aeroslave.com....croz
