Clamp coupling for hose on external thread PP
The straight clamp coupling made of polypropylene (PP) enables the secure connection of spiral hoses with an external thread. It is specially designed for applications where the inner diameter of the hose is crucial.
The coupling is not suitable for flexible or adhesive hoses, solar hoses, or swimming pool hoses, where the outer diameter is decisive.
Thanks to its high resistance to mechanical and thermal stress, weathering, UV radiation, and numerous chemicals, the coupling is versatile—even for food and drinking water.
