STAINLESS STEEL 316 SCREWED THREADED PIPE FITTINGS WITH NPT
Threaded low pressure fittings are also called as 150# fittings or 150 LB threaded fittings. 150# fittings are suitable for low pressure application such as water, oil, and gas. As implied by its name, the pressure rating for 150# fittings is 150PSI, with Screw NPT and BSPT available. The screw low pressure fittings can be in material of SS316, SS304, SS316L and SS304L
The shapes includes screw NPT /BSPT elbow, screw theaded street elbow, NPT /BSPT Tees, Reducing Tees, soft conicial Unions, screw couplings, NPT/BSPT caps, bushings , hose nipples and barrel Nipples. Hex. Nipples.
