Press Fit Water Reducing Coupling - 22 X 15Mm

Press Fit Water Reducing Coupling - 22 X 15Mm

The Press Fit Water Reducing Coupling (22mm x 15mm) is a high-efficiency copper fitting used to connect 22mm copper pipe directly to 15mm copper pipe. Using an "M-Profile" press tool, it creates a permanent, leak-proof mechanical joint without the need for heat, solder, or flux.

Key Technical Specifications

Type: M-Profile Press Fit (Reducing Coupler).

Size: 22mm x 15mm.

Material: High-grade Copper with EPDM O-rings.

Max Pressure: 16 Bar.

Temperature Range: -24°C to 110°C.

Approvals: WRAS and BSI Kitemark approved for potable water and heating systems.

Installation Advantages

Flame-Free: Eliminates the risk of fire and the need for "Hot Works" permits, making it ideal for timber-frame buildings or restricted spaces.

Speed: Installation is up to 3x faster than traditional soldering or compression methods.

Leak Before Press (LBP): Most professional press fittings feature a specific O-ring design that intentionally leaks during a pressure test if the fitting has been forgotten and not pressed, allowing for easy identification of errors.

Installation Best Practices

Preparation: Cut the copper pipe squarely using a dedicated pipe cutter.

Deburring: You must deburr the inside and outside of the pipe. Sharp edges can slice the internal O-ring during insertion, causing a slow leak later.

Marking: Mark the insertion depth on the pipe with a permanent marker. This ensures you can verify the pipe hasn't slipped out before you engage the press tool.

Pressing: Ensure the M-Profile jaws of your tool are correctly aligned over the raised "bead" of the fitting before activating the press cycle.
