PPR Male adaptor hexagonal
In front of the thread, the brass insert has a hexagon that takes a spanner. Holding the adaptor by this hexagon puts the tightening torque into the metal, so a large thread can be made up firmly without straining the bond between the brass insert and the PP-R body.

Description and application
The PPR male threaded adaptor hexagonal is a transition fitting. One end is socket-fused onto PP-R pipe and the other has a brass CW617N BSP parallel (G) male thread that screws into a female-threaded valve, fitting or metal pipe. It is made to EN ISO 15874-3, rated PN25 and available from Ø40x1.1/4" to Ø90x3".
The PPR male threaded adaptor hexagonal from the Eternal line joins a PP-R pipeline to any component with a female thread. One end is a socket for fusion welding onto the pipe. The other end is a brass male thread with a hexagon in front of it. It comes in five sizes, from Ø40x1.1/4" to Ø90x3", in white. The body is PP-R, a random polypropylene copolymer (type 3) made from prime-grade raw material, and the fitting is made to EN ISO 15874-3. It fuses with THERMALINO PP-R pipes into a durable joint built for a long service life. The threaded insert is CW617N brass with a lead content below 2.2 %. The adaptor is rated PN25, with an operating temperature of 70 °C and a maximum of 95 °C. Permissible pressures at each temperature and service life are given in the technical data sheet. The fitting is used wherever PP-R pipework meets a metal or threaded component: valves, pumps, water meters, manifolds, water heaters, storage tanks and existing steel pipework in hot and cold drinking water and heating installations. Because it has a male thread, it screws straight into a female-threaded fitting without an extra nipple. Installation is in two steps. The PP-R socket is joined to the pipe by socket fusion using a PP-R welding tool. The thread is BSP parallel (G), also known as gas thread, and is sealed with a thread sealant suitable for the medium. While the thread is tightened, the brass hexagon is held with a spanner so that the joint between metal and plastic is not loaded. The thread suits BSP female fittings only and does not mate with NPT threads.

Questions
- How do you connect new PP-R plastic pipe to existing galvanised steel pipe in an older building's water supply?
- A PPR male threaded adaptor connects PP-R pipe to galvanised steel pipe: it is fused onto the PP-R pipe and screwed into a female thread on the steel side, such as a socket, tee or valve. The THERMALINO adaptor has a CW617N brass BSP parallel (G) male thread, so the steel fitting must also have a BSP thread. NPT threads have a different form and do not mate with it. If the steel pipe ends in a male thread, a female-threaded steel socket is fitted first. The thread is sealed with a sealant suitable for the medium and tightened by the brass hexagon.
- Which PP-R pipe diameter matches each thread size of the PPR male threaded adaptor, for example for a 2 inch valve?
- Each size of the PPR male threaded adaptor pairs one PP-R pipe diameter with one BSP thread size, so for a 2" valve you use the Ø63x2" adaptor. The range is Ø40x1.1/4", Ø50x1.1/2", Ø63x2", Ø75x2.1/2" and Ø90x3". The first figure is the outside diameter of the PP-R pipe in millimetres and the second is the nominal size of the male thread.
- Can the PPR male threaded adaptor be used on central heating and domestic hot water lines in a commercial building?
- The PPR male threaded adaptor is suitable for domestic hot water and central heating within its rating: PN25, operating temperature 70 °C, maximum temperature 95 °C. It is made to EN ISO 15874-3. The permissible pressure falls as the temperature and required service life rise, so the line should be checked against the pressure-temperature table in the technical data sheet.
- How should the BSP parallel thread of a large PPR male threaded adaptor be sealed and tightened onto a brass valve?
- The BSP parallel thread of the PPR male threaded adaptor is sealed with a thread sealant suitable for the medium, such as PTFE tape or a sealing compound, and tightened with a spanner on the brass hexagon. Holding the hexagon puts the torque into the CW617N brass insert rather than the PP-R body, so a large thread can be made up firmly without straining the metal-plastic joint. Pipe wrenches should not grip the plastic body.
- Can a PPR male threaded adaptor be removed and reused after it has been fused onto a pipe during a plumbing alteration?
- A PPR male threaded adaptor cannot be reused once its socket has been fused to a pipe, because socket fusion makes a permanent joint. The threaded end can be unscrewed from the mating fitting. To change the PP-R side, a qualified installer cuts the pipe behind the joint and fuses on a new adaptor.
