All threaded, special dies required.
Tom is right-on with the stainless,and there is also brass available in class 300 fittings & valves.You may have to go to a "Fluid Power" supply house such as Parker.These valves & fittings look strange,like square blocks rather than nice round shapes,but they work.The supplier you use for other specialty items should be able to direct you to a sourcefor these.Good luck! _______________________________________________ Sprinklerforum mailing list http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field)
