the press crimp groove. This provides the following advantages:
A 20% enlargement of the sealing surface area;
Major reduction of the risk of the sealing ring being pressed
out or damaged;
Fìit makes the pipes insertion easier.

Description of the material used
to produce stainless steel pipes 316L. Unlike traditional systems made with AISI316, INOXPRES®
products present a lower content of carbon that gives a higher
resistance to corrosion.
