HFC35 and 57 Series Polysulfone Couplings

HFC35 and 57 Series Couplings can operate in harsh environments in temperatures from -40°F to 280°F and pressures from vacuum to 125 psi (8.6 bar). The ergonomically designed shrouded thumb latch pad produce a coupling that is easy to grip and simple to operate. An efficient valve design leads to high flow and exceptionally low spillage.

HFC35 Series (White) polysulfone couplings are able to withstand demanding applications and feature physical strength, chemical resistance and autoclavability.

HFC57 Series (Black) polysulfone couplings are UV resistant and able to withstand continued exposure to harmful UV rays without affecting performance.

Colder HFC35 and HFC57 Series couplings are compatible with HFC12 Series Couplings.
