SS 304 & 316 Stainless Steel Sanitary Pipe Fitting
Our SS 304 & 316 Stainless Steel Sanitary Pipe Fittings are engineered to meet the most stringent hygienic requirements of the food & beverage, pharmaceutical, biotechnology, and cosmetic industries. As essential components in hygienic process piping systems, these precision-manufactured elbows, tees, and complementary fittings ensure product purity, prevent contamination, and facilitate efficient cleaning procedures.
Manufactured from certified AISI 304 or superior corrosion-resistant 316/316L stainless steel, these fittings feature crevice-free designs with polished internal surfaces that exceed industry standards for cleanability. Available with multiple connection options including Tri-Clamp and orbital butt weld, they provide versatile solutions for both permanent installations and systems requiring frequent disassembly for maintenance or batch changeovers. Each fitting is designed with zero dead legs to prevent bacterial harborage and is fully compatible with Clean-in-Place (CIP) and Sterilize-in-Place (SIP) procedures, ensuring compliance with global sanitary regulations and GMP requirements.
