RIIFO MLCP F18 Female Threaded Tee

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.
