This MDPE straight coupling is ideal for DIYers and professional contractors looking to join 25mm MDPE pipes in water and irrigation systems. It offers a secure, leak-free connection without requiring specialized heat-welding tools; however, users must ensure the pipe ends are cut perfectly square to guarantee a proper seal within the compression fitting.

No, this is designed for standard cold water MDPE systems and is not rated for high-temperature applications.
No, the seal is created by the internal compression gasket, not the threads. PTFE tape is unnecessary and may interfere with the fit.
Yes, provided the internal O-ring is undamaged and the threads are clean, it can typically be reinstalled.
PN10 is a pressure rating that signifies the fitting is rated for up to 10 bar of working pressure.
Yes, standard MDPE compression fittings are generally constructed from materials suitable for potable cold water supply, but always check local plumbing codes.
Ensure the pipe is pushed fully into the fitting and the nut is tightened securely. Check that the pipe surface is smooth and free of deep scratches.
Check for burrs on the pipe end and ensure the compression nut is sufficiently loosened to allow the internal seal to expand.
Installation is straightforward: ensure your pipe end is cut clean and free of burrs. Loosen the compression nut on the coupling, slide the pipe into the fitting until you feel it meet the internal stop, and tighten the nut firmly by hand. While hand-tightening is often sufficient, a strap wrench can be used for final tensioning if necessary. Avoid using pipe wrenches with metal teeth, as they can scratch the plastic casing. Periodically inspect joints after initial pressurization to ensure no slow leaks have developed, especially after ground settling.
