Home Range Coupling - 22mm X 3/4" Compression To Female Iron

No, this is a compression fitting and does not require soldering. It creates a secure mechanical joint.

Yes, it is suitable for 22mm copper pipe and 22mm plastic pipe, provided you use the correct pipe inserts (stiffeners) with plastic pipe.

Female Iron (FI) thread refers to a parallel (straight) internal thread, typically found on plumbing fittings. It is designed to connect to a male (parallel) iron pipe thread.

Tighten the nut firmly with two wrenches until a secure seal is achieved. Avoid overtightening, which can damage the fitting or pipe. Consult manufacturer guidelines if available, but hand-tight plus a quarter to half turn with a wrench is often sufficient.

This coupling is designed for standard domestic water pressure. For very high-pressure commercial or industrial applications, consult product specifications or a qualified professional.

Use a soft, damp cloth and mild soap if necessary. Rinse and dry thoroughly. Avoid abrasive cleaners or scouring pads.

Ensure the pipe is fully inserted, the olive is correctly positioned, and the compression nut is adequately tightened. Check for any damage to the pipe or olive. If leaks persist, consider replacing the olive and re-tightening.

Verify that the correct size wrenches are being used and that they are gripping the nut and body securely. Ensure no debris is interfering with the threads. Do not force the nut if significant resistance is met; check for cross-threading or misalignment.

Confirm that a compatible pipe insert (stiffener) is being used with the plastic pipe. The insert is crucial for preventing the pipe from collapsing under the compression force.
