HFC35 NSF

HFC35 Series polysulfone couplings are able to withstand demanding applications and feature physical strength, chemical resistance and resistance to cleaning solutions (used in flushing tubing and hose lines) and are autoclavable. An ergonomic design and a large, shrouded thumb latch 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 NSF parts are listed under the criteria of the NSF/ANSI Standards.
