The 25mm MDPE Straight Compression Coupling to 1" BSP Male is a specialized plumbing component designed for professional installers and DIY enthusiasts who need to transition from metric MDPE piping to standard imperial threaded fittings. This fitting is ideal for municipal water supply systems, agricultural irrigation, and industrial fluid transport, providing a robust and corrosion-resistant connection. While it excels in durability and ease of installation, users should be aware that it is specifically designed for 25mm MDPE pipe and will not accommodate larger or smaller metric pipe sizes without the use of additional adapters.

No, this is specifically designed for MDPE (Medium Density Polyethylene) piping.
This product is generally intended for cold water supply systems. Please check local plumbing codes before using with high-temperature applications.
No, it can be installed using standard hand tools like a wrench for the final tightening.
Yes, its corrosion-resistant material makes it suitable for direct burial in most soil conditions.
PN10 refers to the pressure nominal rating, meaning the fitting is rated for a maximum working pressure of 10 bar.
No, this uses BSP (British Standard Pipe) threads, which are not directly compatible with NPT (National Pipe Taper) threads.
Ensure the pipe is inserted fully past the internal seal and that the nut is tightened evenly. Check the internal O-ring for debris.
Disconnect the fitting and apply a fresh layer of PTFE tape to the 1" BSP threads before re-tightening.
To install, ensure the 25mm MDPE pipe end is free of burrs and debris. Loosen the compression nut on the fitting, slide the pipe through the nut and seal, and push firmly until the pipe hits the internal stop. Tighten the nut firmly by hand or with a wrench until snug; avoid over-tightening to prevent damage to the plastic threads. For the threaded end, always apply PTFE tape to the male BSP threads before connecting to your female component to prevent seepage. Inspect the connection annually for signs of moisture or vibration-induced loosening.
