Compression fittings for PEX and multilayer pipe

For your heating and plumbing installations with PEX tube and multilayer tube rmmcia has prepared the family of compression fittings for PEX and multilayer pipe. A complete range of connection fittings including changes of direction, branches, plugs, straight unions, manifolds, stopcocks, etc., in versions coupling - coupling for connecting pipes and coupling - threaded for connecting threaded pipe or fittings.

This family of brass fittings allows for the connection of cross-linked polyethylene pipe (PE-X) and multilayer pipe (plastic tube with a sandwiched layer of aluminium). On the coupling ends, the union with the polyethylene tube is sealed by O-rings placed on the removable insert that is introduced into the fitting body and into the tube. The assembly is tightened by the nut that compresses the clamp, leaving the tube subject and the connection tight. In case of multilayer pipe, and additional Teflon washer is placed on the bottom side on the insert in contact with the tube, to avoid electrolysis effects with the aluminium part.

In the different articles of the family the references with different sizes are identified in inches or fractions of an inch for the threaded end, and in millimetres for the coupling end in reference to the outer diameter and thickness of the corresponding polyethylene tube. Examples of applications may be plumbing for water supply and distribution, hot water feeding for radiators and underfloor heating.

In terms of manufacturing materials and their qualities, we have brass CW617N UNE-EN 12165 for hot forgings (nut and body), brass CW614N UNE-EN 12164 for parts machined from bar (clamp and insert) and synthetic rubber EPDM 70 for O-ring seals.

The design and manufacture of this family of compression fittings conforms with standard UNE-EN 1254-3 in reference to fittings with compression ends for use with plastic pipes, on UNE-EN ISO 15875-3 for fittings applied to PE-X piping for hot and cold water, UNE-EN ISO 228 for the threaded ends, UNE-EN 1254-5 for fitness for purpose of the system; and in relation with manufacturing the processes are done under certified procedures conforming to ISO 9001 to ensure a high quality production and an effective and durable use over time.
