FORGOT YOUR DETAILS?

inoxPRES is the Pressfitting system by Raccorderie Metalliche perfectly matching stainless steel features with the benefits of the pressfitting system.


inoxPRES material AISI 316L, 304, 444 stainless steel.


Fittings in 316L stainless steel can be fitted to a wide range of pipes, from 15 to 108 mm diameters, in 316L, 304 and 444 steel. Joints are fitted with an “M-shaped” profile toroidal chamber, optimised thanks to RM experience, where a patented profiled O-Ring is fitted directly at the end of production. The wide range of inoxPRES pipes and pipe fittings are approved by many international certification institutions. Besides the 30 certification obtained, some apply to the potable water, compressed air, natural gas, service and fire protection water transportation.

Where to use inoxPRES?

Products and services are developed to solve at best any installation problem and issue, aiming at quality, safety and speed.

Stainless steel is the best solution where water purity and hygiene matter. From potable water plants, water adduction in industrial processes up to clinics where periodically a chemical and thermal disinfection is enforced. inoxPRES by Raccorderie Metalliche offers the best possible quality of materials and safety guarantee. “Visible” inoxPRES installations provide for a higher degree of hygiene and clearing. O-Rings can be used between -20 to +120°C, maximum pressure 16bar providing for quality and safety as well.

Pressfitting Systems

The junction connection of RACCORDERIE METALLICHE press fttiing systems is with “M” contour. During the pressing process a deformation takes place on two planes. The first plane creates a permanent connection and provides mechanical strength through the mechanical deformation of the press fitting and the pipe. On the second plane the seal ring is deformed in its cross secoon and through its elastic properties creates the permanently tight joint.

Sealing ring profile (o-ring)

Traditional press fttiing systems use round sealing rings, which can easily be damaged by careless fning. RM on the other hand uses a patented sealing ring with a lenticular profile which fits 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;

•    Flit makes the pipes insertion easier
