Tri-Clamp Fittings - Adapters
PNW Sanitary Tri-Clamp Adapter Fittings provide a reliable connection between sanitary process lines and threaded or butt-weld equipment. Designed for seamless integration into food, beverage, dairy, brewery, cosmetic, nutraceutical, and pharmaceutical systems, these adapters simplify transitions between Tri-Clamp, NPT, and weld-style connections while maintaining full 3-A sanitary compliance.
Manufactured from 304 and 316L stainless steel and polished to a 32Ra sanitary finish, each adapter offers a smooth, crevice-free surface for optimal cleanability and flow. These fittings are dimensionally interchangeable with industry-standard sanitary components and are available in multiple configurations, including Tri-Clamp x Male NPT (21MP), Tri-Clamp x Female NPT (22MP), Butt-Weld x Male NPT (19WB), and Butt-Weld x Female NPT (22WB). Material Test Reports (MTRs) are available upon request.
