The Pepte 22mm Compression Straight Coupling (MPN: B175) is designed for professional plumbers and DIY enthusiasts who need a reliable way to join two lengths of 22mm pipework in a straight line. This fitting provides a robust, leak-resistant connection through a mechanical compression seal, eliminating the need for hot work or soldering. While it is highly versatile and WRAS approved for hot and cold water systems, users should ensure the pipe ends are cut squarely and deburred properly to guarantee a secure, long-lasting seal.

No, compression fittings rely on the olive creating a metal-to-metal seal against the pipe and the coupling seat. Tape is not typically required or recommended.
While the coupling body is reusable, it is recommended to replace the olive if you disassemble the connection, as the olive is permanently deformed during the first installation.
This fitting is designed for copper piping. If using with plastic pipe, ensure you use a supporting pipe insert (stiffener) inside the plastic pipe to prevent crushing.
You will need two adjustable wrenches or pipe grips—one to hold the coupling body and one to tighten the nut.
Yes, this product is WRAS approved, meaning it has been tested to meet strict standards for safety in contact with drinking water.
Tighten the compression nut by another quarter turn; if it continues, disassemble the joint to inspect the olive for damage or ensure the pipe end was properly deburred.
Check the pipe end for burrs or deformation from cutting; use a file to smooth the edge and ensure the pipe is round.
To ensure a successful installation, follow these steps:
Compatibility: Designed exclusively for 22mm piping. Ensure system pressure remains within standard residential limits. Care: Periodically inspect joints for signs of moisture or weeping. Do not overtighten, as this can deform the olive and cause leaks.
