Engineered for a secure and leak-proof transition from plastic piping to metal equipment, our Industrial UPVC male threaded adaptor DIN PN16 delivers unmatched reliability. Manufactured directly by Huiya, these precision-threaded fittings are injection-molded exclusively from 100% virgin resin. By strictly avoiding recycled materials, we eliminate the risk of thread shearing and structural weakness under high-torque installations.
As a premium PVC-U engineering solution, this male adaptor provides outstanding acid & alkali resistant performance, preventing degradation even when handling highly corrosive fluids. Unlike standard commercial plastics, Huiya’s thick-wall rigid PVC fittings are rigorously designed to safely withstand continuous industrial-grade PN16 high pressure (16 Bar) without the risk of bursting or deformation.
Available in a comprehensive range up to DN100, it is the ultimate transition fitting for any demanding chemical processing plant and rigorous industrial water treatment facility. To complete your reliable fluid control system, explore our full catalog of [UPVC pipe fittings PN16].
