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.

Installation Instructions

  1. Cutting: Cut the multilayer pipe perpendicular to its length, taking care not to damage the pipe when removing any packaging beforehand. A clean, square cut is essential, as an improperly cut end can cause the finished joint to leak. For pipe diameters of 32mm and above, a wheel pipe cutter should be used.

  2. Round & Bevel: Using a bevelling tool that matches the pipe diameter, push the tool fully onto the pipe until the blades engage, then rotate it clockwise several times. The calibrating mandrel restores the pipe to a true circle while the blades cut an even bevel, allowing the pipe to enter the fitting without catching or damaging the O-rings. If a drill-driven tool is used, keep the speed below 500 rpm.

  3. Inspection: Check the pipe visually for damage or impurities and confirm the bevel is uniform around the full circumference before proceeding. A few seconds of inspection here prevent a failed joint later.

  4. Insertion: Select a fitting matching the pipe diameter, align it with the pipe, and push the pipe in until it seats against the fitting shoulder. Correct insertion depth is confirmed when the pipe is visible through the inspection windows in the fitting sleeve.

  5. Jaw Selection: Attach a press jaw or insert of the correct profile and diameter to the pressing tool, checking both are in good working condition. Note that while F18 fittings are multi-profile, the jaws sit differently on the press sleeve: a TH jaw locates with its wide groove over the plastic fixing ring, while a U jaw fits directly onto the metal sleeve using the edge of the fixing ring as its stop.

  6. Pressing: Make sure the pipe and fitting are completely free of stress, then close the jaw and complete the press. With a battery or electric tool, the cycle is complete when the jaw is fully closed, and most machines signal this. With the manual pressing tool, close the handles in one smooth, continuous motion until the touch points on the handles meet, without releasing until the jaw has fully closed. Each connection must only ever be pressed once. Open the jaw, remove the tool, and the joint is complete.
