## Summary description

Unidelta transition coupling model 601541 connects 40 mm PE (polyethylene) pipe to a 6/4" male threaded fitting. The coupling provides a durable mechanical transition between plastic PE piping and threaded metal or plastic components. Suitable for water supply and irrigation systems where a reliable pipe-to-thread connection is required, enabling quick installation and leak-resistant joining.

## Long description

Unidelta transition coupling 40 mm PE to 6/4" male threaded (model 601541) is designed to connect 40 mm polyethylene (PE) pipe to a 6/4" male threaded fitting. The coupling creates a mechanical junction between smooth PE pipe and threaded components, providing a watertight interface suitable for water supply and irrigation installations. Constructed for compatibility with standard 40 mm PE piping and standard 6/4" male threads, the fitting enables straightforward connection of metal or plastic threaded valves, adapters and accessories.
Advantages
The coupling offers a robust, leak-resistant transition between PE pipe and threaded fittings without requiring heat fusion or complex adapters. Its design allows quick installation using common plumbing tools and ensures a secure mechanical grip on the pipe. Made for outdoor and indoor water systems, the component resists common stresses in supply and irrigation lines and reduces the need for custom machining or specialty parts.
Suitable for
Domestic and commercial water supply lines
Irrigation systems and garden watering networks
Connections to threaded valves, taps or adapters
Repair or modification of existing PE pipe installations
Key specifications
Pipe compatibility: 40 mm polyethylene (PE) smooth pipe
Thread type: 6/4" male threaded connection
Function: mechanical transition coupling between PE pipe and threaded fittings
Typical application: potable water and irrigation systems
Installation method: mechanical compression/connection to pipe and thread engagement to fitting
How to use
Prepare the 40 mm PE pipe by cutting it square and deburring the cut end. Slide the coupling components onto the pipe according to the manufacturer’s assembly order, ensuring the pipe is fully inserted to the marked stop or recommended depth. Tighten the compression or clamping element to secure the pipe, then engage the 6/4" male thread to the corresponding female fitting and tighten to the appropriate torque for a leak-free connection. After installation, inspect the joint for proper seating and perform a pressure check according to system requirements.
Usage recommendations
Use compatible 40 mm PE pipe and standard 6/4" female threaded fittings. Follow recommended torque values for threaded connections and recheck tightness after initial pressure testing. Avoid solvents or aggressive chemicals near the joint and perform regular inspections in exposed installations to ensure long-term reliability.
