Tri-Clamp x Male NPT Adapter (21MP) – 304 Stainless Steel

Manufactured from 304 stainless steel and 3-A Certified, these adapters deliver durable, 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 and easy cleanability.
