The Pepte 22mm x 15mm compression reducing coupling is an essential component for DIY enthusiasts and professional plumbers looking to transition between different pipe sizes in a single line. This high-quality brass fitting provides a secure, leak-free connection for domestic and commercial plumbing systems without the need for specialized soldering equipment or high-heat tools. While it offers a reliable and quick installation, users must ensure the pipe ends are cut square and deburred correctly to prevent potential leaks at the compression seal.

No, this is a compression fitting that uses a metal olive to create a seal, meaning no soldering or heat is required.
Yes, but you must use a suitable pipe insert to prevent the plastic pipe from deforming under the pressure of the compression olive.
Yes, this coupling is WRAS approved, making it safe for use in domestic potable water systems.
It is generally recommended to keep compression joints accessible for future maintenance, though they are durable enough for long-term use if installed correctly.
You will need a pipe cutter or hacksaw, a file for deburring, and two adjustable spanners or wrenches.
Tighten the nut by a quarter-turn at a time. If it still leaks, disassemble, check that the pipe is cut square and deburred, and ensure the olive is correctly positioned.
Check that the threads are clean and not cross-threaded. Ensure you are not using excessive force that may be stripping the threads.
Verify that the pipe has been inserted past the olive and reaches the internal stop of the coupling.
To install, first cut the pipe cleanly to ensure a square edge, then use a deburring tool to remove any sharp burrs that could damage the compression olive. Slide the nut and olive onto the pipe, insert the pipe into the coupling body, and tighten the nut by hand before finishing with a spanner. Ensure the coupling is compatible with copper or plastic piping that conforms to standard metric sizes. Periodic inspection is advised for any plumbing joint; check for moisture during the first 24 hours of operation to ensure the seal is set correctly. Avoid over-tightening, as this can crush the olive and cause the very leaks you are trying to prevent.
