This one helps me when I'm not sure where else to go: http://www.thomasregister.com/ Let's you search by product or service, company name, and/or brand name.

Here's a list of manufacturers with National in their name. Not sure which one it would be but would first guess the Natinal Piping Products one.

Erby: Thanks. I should have thought of the Thomas Register. I'll check it out. I spoke with a local sprinkler guy and he came up with some comments to the effect that ANY glycol-filled system, no matter how good or well-installed the fittings, eventually leaks. Anybody heard of that one? I'm thinking of anti-freeze in a car....Hmmmmmm.

He also said that a bunch of cheap mechanical tees ended up in the US from the Middle East somehow... R
