Unidelta equal straight coupling PE 25 x 25 mm for polyethylene pipes, model 601025

Unidelta equal straight coupling PE 25 x 25 mm (model 601025) is a mechanical connector designed to join two polyethylene (PE) pipes of the same 25 mm nominal diameter in a straight line. Intended for water supply, irrigation and low-pressure fluid distribution systems, this coupling provides a secure, leak-resistant connection between PE pipe ends while maintaining internal flow continuity and pipe alignment.

Advantages

The coupling offers a compact, stable connection that simplifies on-site assembly and replacement of PE pipes. Its equal straight design ensures alignment without altering pipe geometry, and the mechanical joint reduces reliance on solvent welding or heat fusion equipment. Constructed for compatibility with common PE pipe materials, the product helps maintain flow capacity and basic corrosion resistance typical for polyethylene systems.

Suitable for

• Domestic and municipal low-pressure water supply lines
• Irrigation systems for gardens, lawns and small agricultural plots
• Temporary or permanent extensions of existing PE piping
• Garden and landscape watering systems and dripline networks

Key specifications

• Pipe type compatibility: polyethylene (PE)
• Nominal diameter: 25 x 25 mm (equal straight coupling)
• Connection type: mechanical push-fit/insert coupling suitable for same-diameter pipes
• Flow orientation: inline straight connection to preserve internal flow
• Typical applications: low-pressure water and irrigation distribution

How to use

Prepare the PE pipe ends by cutting them square and removing any burrs or debris to ensure a clean mating surface. Slide the coupling onto one pipe end, then insert the second pipe fully into the opposite side until the pipes meet the internal stop or sealing element. Apply steady axial pressure to ensure complete insertion and check alignment. After assembly, verify the joint by performing a low-pressure system test to confirm there are no leaks before putting the line into regular service.

Usage recommendations

For reliable performance, use the coupling with PE pipes that meet manufacturer specifications for wall thickness and material. Avoid using this mechanical coupling on systems that require high-temperature operation or high-pressure ratings beyond typical irrigation and low-pressure supply limits. When installing outdoors, protect the joint from prolonged UV exposure where possible and inspect periodically for mechanical damage or deterioration.
