Stainless Steel High Pressure Fittings for Spiral Pipe

A wide variety of round fittings are produced for high pressure including 90, 60, 45 and 30 degree elbows as standards, tees, laterals, reducing laterals, reducers, couplings, end caps, crosses, etc.

Fitting ends are made with two inch male sleeves. Standard fittings have built-in slip type beaded couplings.
