It is basically an o-ring supplier but has references to military specs both fluids and seals. There is a very large o-ring sizing chart. For instance the number for sphere o-rings would be AS568A-128.

IT IS NOT AS COMPLETE AS A PARKER O-RING REFERENCE GUIDE SO DO NOT MAKE INFERENCES FROM WHAT YOU SEE HERE BUT RATHER USE THE INFO TO FOR FURTHER INVESTIGATION. For instance, there is a reference to Dextron in one of the columns. THIS IS NOT THE SAME AS DEXRON. Misinterpreting this could be catastrophic. Spend some time looking in all the sections. This is the best I've seen on the web. If there is a better one let's hear about it.

http://www.aceseal.com/products.html Ace Seal in CA has all of the o rings needed in the SM engine. Down load their catalog from the left side bar button, "catalog download"

Be advised that:

  • brake fluid seals = EPDM
  • green fluid seals = Nitrile

Viton is a high temperature replacement for Nitrile.
