Unidelta transition fitting PE male thread 40 mm x 5/4" (601540)

Unidelta transition fitting PE male thread 40 mm x 5/4" is a mechanical connector designed to join polyethylene (PE) pipe with a 40 mm outer diameter to a 5/4" male threaded component. The fitting enables a sealed transition between PE piping and threaded valves, meters or fixtures in water and utility installations. Constructed for compatibility with standard PE pipe dimensions, it provides a compact and reliable solution for changing from a smooth-walled pipe system to a threaded connection without solvent welding or complex adapters.

Advantages

The Unidelta transition fitting ensures a stable mechanical connection between PE pipe and threaded components while maintaining flow continuity and minimizing the risk of leaks when correctly installed. Its design allows for straightforward assembly, reduced installation time and compatibility with common plumbing and irrigation systems. Made to withstand typical operating pressures in distribution and service lines, the fitting supports long-term use in potable and non-potable water systems when used with appropriate sealing materials.

Suitable for

• Connecting PE pipelines to threaded valves and meters
• Domestic and commercial plumbing repairs and extensions
• Irrigation systems and garden water distribution
• Utility and service line transitions where a threaded connection is required

Key specifications

• Connection type: PE pipe to male threaded fitting
• PE pipe diameter: 40 mm (outer diameter)
• Thread size: 5/4" male
• Material: corrosion-resistant polymer/plastic suitable for PE systems
• Typical application: water and utility conveyance

How to use

Prepare the PE pipe by cutting a clean, square end and deburring the inside and outside edges to ensure proper seating. Insert the PE pipe into the fitting according to the manufacturer’s installation method, ensuring the pipe reaches the correct insertion depth. Tighten the threaded connection to the mating component using appropriate tools and sealing tape or sealant on the male threads to prevent leakage. Follow any torque recommendations and allow assembled joints to be pressure-tested according to local codes before putting the system into regular operation.

Usage recommendations

Use compatible PE pipe and follow Unidelta installation instructions. Apply thread sealing tape or approved sealant on the male threads and perform pressure testing after installation. Avoid exposure to temperatures and chemicals outside the material specification to maintain service life.
