The wide range of available fasteners and connection allows you to perform various types of installations. The main advantages of the system COPRAX are listed below:

- a wide range of pipe diameters and accessible fittings,
- low weight of the installation
- high tightness and durability of fittings,
- reduced production costs,
- easy way of making the installation
- hygienic installations performed and confirmed by the relevant Certificates. Pneumatic installations, that are made basing on COPRAX system can by assembled by yourself after reading user’s manual. We also offer a wide range of tools for the implementation and installation such as trimmers, cutters, welders, etc.


1. Cutting the pipe by a shear.
2. Topimy outer and the inner surface of the pipe fittings.
3. Insert pipe into the fitting to melt and hold the depth / g as indicated in the table below.
