PPR Union adaptor f/f

The THERMALINO PPR brass union f/f joins a PP-R pipe by socket fusion to a female BSP parallel thread through a detachable CW617N brass union, so the connection can be opened later without cutting the pipe. It is rated PN20, made to EN ISO 15874-3 and available from Ø20 to Ø63.

The PPR Union adaptor f/f from the THERMALINO Eternal line is a transition fitting for PP-R pipeline systems. It has a female socket on the plastic side, welded to the pipe by socket fusion, and a detachable brass union with a female BSP parallel thread, also called gas thread, on the other side. Because the union can be opened and closed again, it suits connections that may need to change over time, such as towel radiators and expansion vessels, and joints that need easy access for repair. The plastic body is made from prime-grade PP-R, a random polypropylene copolymer (type 3), and conforms to EN ISO 15874-3. The fitting is designed for socket fusion with THERMALINO PP-R pipes, giving a homogeneous weld and a long service life. The insert is CW617N brass with a lead content below 2.2 %, in line with European norms. The nominal pressure is PN20, with an operating temperature of 70 °C and a maximum temperature of 95 °C. The permissible pressure at each temperature is given in the technical data sheet. This PPR brass union is used in hot and cold water supply and central heating installations in houses, apartment buildings and commercial buildings. It is available in Ø20, Ø25, Ø32, Ø40, Ø50 and Ø63, and in white and grey. To install it, the installer welds the PP-R socket to the pipe with a socket fusion tool, then connects the threaded part to the equipment or male-threaded fitting. The work on pressurised water and heating lines is carried out by a qualified installer.
