Hose screw connections of PA, polypropylene, PVDF, PFA:

The hose screw connections made of polyamide, polypropylene, PVDF and PFA are suitable for connecting hose lines in the chemical, pharmaceutical and food area. These connections are used where push-in fittings or hose screw connections made of brass, POM or aluminium cannot be practically used due to technical basic conditions (e.g. for very soft hoses, vacuum applications, liquids, for strong movements between hose and connection or necessary chemical resistance). As a rule these connections are used with hoses made of polyamide (stable), PE (economical, but kink sensitive) or PTFE (highly resistant). In every case we recommend testing the most economical material stainless steel.
