The copper pipe system

Solid and proven

Copper is a versatile material. Equally versatile are the applications of the thin-walled COPPERFIX copper press fitting system. It is state-of-the-art and, moreover, utterly simple to install.

Further advantages include the low thermal expansion, the large cross-section and the non-detachable press connection, which makes COPPERFIX copper pipe systems unbeatably leakproof.

COPPERFIX press fittings are made of CU-DHP (hot-drawn fittings)  material, as well as bronze material 2.109 (threaded fittings).
The COPPERFIX press fittings are “leak before pressed” and fitted with EPDM gaskets in the factory.
