PPR Elbow 90° f/f

The PPR Elbow 90° f/f is a socket fusion fitting that turns a PP-R pipeline through a right angle, with two female sockets that take pipe of the same diameter. Rated PN25 and made to EN ISO 15874-3, it is used in hot and cold water and heating lines from Ø20 to Ø63.

The PPR elbow 90° f/f from the THERMALINO Eternal line turns a PP-R pipeline through a right angle. It is fitted at every corner, riser and change of route in a building's water network, which makes it one of the fittings an installer uses most often in a PP-R installation. Both ends are female sockets, so pipe of the same diameter enters the fitting directly on each side. It is made of PP-R to EN ISO 15874-3, the part of the standard covering polypropylene fittings for hot and cold water installations. With nominal pressure PN25, operating temperature 70 °C and maximum temperature 95 °C, it serves hot water and central heating lines as well as cold water supply. The range covers Ø20, Ø25, Ø32, Ø40, Ø50 and Ø63, in white, grey and green, so the elbow can match the pipe used on site. The elbow is joined by socket fusion. The pipe is cut square and cleaned, the pipe end and the fitting socket are heated together on a fusion welder fitted with heads of the right diameter, and the pipe is pushed straight into the socket without twisting. Once cooled, pipe and fitting form a single homogeneous joint, with no threads, sealant or cement. Heating, joining and cooling times depend on the diameter and follow the welding tool's table. Where the line meets a tap or valve, a PPR fitting with a threaded insert is used at that point. Pressure ratings at each temperature and service life, and the dimensions of each size, are in the technical data sheet.
