SS201 SS304 SS316 50PSI NPT BSPT STAINLESS STEEL SCREWED THREADED PIPE FITTINGS
stainless steel pipe screw fittings are excellent for uses that involve chemicals or liquids that may be corrosive. Along with fighting corrosion,
a stainless steel pipe fitting will prevent contamination making it useful to many professionals. 304 Stainless Steel is economically priced,
chromium-nickel material that offers very good corrosion resistance. 316 Stainless Steel has higher nickel content and contains molybdenum for even better corrosion resistance
The screw types can NPT as per ASME B 1.20.1, BSPP BSPT as per BS21, DIN2999, The investment Stainless castings conform to
ASTM A351 ACI Grade CF8 (304) & ACI Grade CF8M (316)
