Tri-Clamp x Male NPT Adapter - 1.500" Tri-Clamp x 1-1/2" MNPT - (21MP) - 316L Stainless

Tri-Clamp x Male NPT Adapter (21MP) – 316L Stainless Steel

PNW Sanitary Tri-Clamp x Male NPT Adapters (21MP) provide a secure, leak-resistant transition between sanitary Tri-Clamp process lines and threaded NPT equipment, valves, or pipe fittings. Manufactured from 316L stainless steel and 3-A Certified, these adapters offer superior corrosion resistance and long-term hygienic performance in food, beverage, dairy, brewery, cosmetic, nutraceutical, and pharmaceutical systems.

The Tri-Clamp side mates with standard ferrules and gaskets, while the precision-machined male NPT threads into compatible female fittings for a tight, reliable seal. Each adapter is polished to a 32Ra sanitary finish for smooth flow, easy cleanability, and chemical resistance during CIP/COP operations.
