Transition coupling Unidelta PE male thread 40 mm x 1" (601539)

Unidelta transition coupling PE male thread 40 mm x 1" is a mechanical fitting designed to connect 40 mm polyethylene (PE) pipes to components with a 1" male threaded connection. The coupling creates a secure transition between flexible PE piping and threaded valves, appliances or fittings, ensuring a tight seal and stable connection without the need for solvent welding or specialized adapters. It is intended for use in potable water distribution, irrigation systems and general plumbing installations where PE pipeline meets threaded equipment.

Advantages

The coupling provides a reliable mechanical connection that compensates for small misalignments and pipe movement while maintaining flow integrity. Its design allows simple installation using standard tools, reducing installation time compared with more complex transition methods. The fitting's materials and construction deliver resistance to corrosion and long service life in typical water and irrigation environments.

Suitable for

• Connecting 40 mm PE pipes to 1" threaded valves and fittings
• Irrigation mains and branch lines
• Domestic and commercial water distribution systems
• Temporary or permanent connections to appliances with 1" male threads

Key specifications

• Pipe connection: polyethylene (PE) socket for 40 mm outer diameter pipe
• Thread connection: 1" male threaded outlet compatible with standard plumbing threads
• Connection type: mechanical transition coupling for joining PE to threaded components
• Application medium: water for irrigation, potable supply and general plumbing
• Material characteristics: corrosion-resistant materials suitable for wet environments

How to use

Prepare the PE pipe by cutting a square, clean end and deburring the inner and outer edges. Insert the pipe into the PE socket of the coupling to the required depth and secure according to the coupling's assembly method (for example, compression or clamping mechanism), ensuring an even, fully seated joint. Apply suitable thread sealant or PTFE tape to the 1" male thread before engaging the mating threaded fitting and tighten to the appropriate torque. After assembly, check the connection for leaks under normal working pressure and make any additional adjustments as necessary.

Usage recommendations

Verify pipe dimensions and thread compatibility prior to installation and follow local plumbing and irrigation standards. Use correct hand or powered tools to achieve a consistent seal without over-tightening. Periodically inspect joints in service for signs of leakage or movement, especially in exposed or buried installations.
