## Long description

Unidelta Transition Fitting PE Female Thread 25 mm x 1" is a plumbing adapter designed to join 25 mm polyethylene (PE) pipe to a 1" female threaded component. The fitting provides a secure mechanical connection between PE distribution tubing and threaded valves, meters, or fixtures, enabling a reliable transition from plastic pipework to conventional threaded plumbing parts.
Advantages
The adapter combines a PE-compatible compression connection with a standard 1" female thread to simplify installation without specialized tools. Constructed to resist typical stresses in water distribution and irrigation systems, the fitting ensures leak-resistant performance when properly installed. Its compact design minimizes protrusion at connection points and supports straightforward maintenance or replacement of threaded components.
Suitable for
 Connecting 25 mm PE pipe to 1" female threaded valves and fittings
 Irrigation mainlines and branch connections
 Water metering interfaces requiring a threaded inlet or outlet
 Temporary or permanent plumbing connections between plastic pipe and threaded fixtures
Key specifications
 Pipe compatibility: polyethylene (PE) pipe with outer diameter of 25 mm
 Thread type: 1" female threaded outlet suitable for standard plumbing fittings
 Connection method: compression-style transition for PE pipe to threaded component
 Typical application: water distribution, irrigation, and plumbing transitions
 Form factor: compact inline adapter designed for easy installation in supply lines
How to use
Prepare the 25 mm PE pipe by cutting it squarely and ensuring the pipe end is clean and free of burrs. Insert the PE pipe into the compression side of the fitting until it reaches the internal stop, then tighten the compression nut or collar according to manufacturer torque guidance to secure the pipe. Thread the 1" female end onto the corresponding male threaded component using appropriate thread sealant or tape as required for the application. After assembly, pressurize the system and inspect the joint for leaks, retightening if necessary following recommended torque limits.
Usage recommendations
Use compatible PE pipe (25 mm OD) and check that the mating male thread conforms to standard 1" dimensions. Where potable water is involved, ensure all seals and sealing materials are approved for drinking water systems. Avoid excessive mechanical stress or bending at the connection point and perform periodic inspections for tightness and integrity in line with local plumbing or irrigation maintenance practices.
