Description
Bridging the gap between multilayer pipe and copper pipework, this spigot adaptor gives installers a straightforward way to transition from one material to the other without soldering, brazing or additional compression fittings on the press side. The press end is built to the same standard as the rest of the F18 range, combining a stainless steel sleeve, PE collar and EPDM o-rings around a CW167N brass body, while the opposite end is finished as a plain spigot sized to suit standard copper pipe diameters.
The press connection includes leak before press (LBP) protection, so a joint that hasn't been fully closed will leak on testing rather than staying hidden once the system is filled and running. It accepts TH and U profile pressing jaws, and remains adjustable after pressing, giving some flexibility in lining the copper-side connection up correctly once the main run is in place.
Rated to a maximum working pressure of 10 bar and an operating range of -25°C to +95°C, this adaptor is suited to transitioning between multilayer and copper pipework in domestic and commercial hot and cold water systems, and holds WRAS approval for potable water use.
The standard version terminates in a plain brass spigot, ready to be jointed into existing copper pipework using compression fittings, solder, or push-fit connectors on site. The extended version has a length of copper tube already fitted to the spigot, in its natural, unplated finish, giving a ready-made transition piece where a longer or pre-formed copper tail is more practical than joining onto separate pipe on site.


Key Features & Benefits
- Material transition without soldering: Connects multilayer pipe to copper pipework using a press fit on one side and a plain or pre-fitted spigot on the other.
- Leak before press protection: The press connection will leak on testing if not fully closed, catching any fault before the system is commissioned.
- Multiple jaw compatibility: Works with TH, B and U profile pressing jaws, keeping tooling options open.
- Choice of spigot or fitted tail: Available as a plain brass spigot for jointing on site, or with a copper pipe tail already attached for a ready-made transition.
