Unidelta elbow PE to female threaded fitting 25 mm x 1" (602626)

Unidelta elbow PE to female threaded fitting 25 mm x 1" is a polyethylene 90° elbow designed to connect a 25 mm PE pipe to a 1" female threaded component. The fitting combines a PE socket for secure insertion of polyethylene piping with a female threaded port compatible with metal or plastic male threads. It is intended for water and low-pressure fluid systems where a compact change of direction and a reliable threaded connection are required.

Advantages

This polyethylene elbow provides chemical resistance and corrosion-free performance typical of PE materials, ensuring durability in outdoor and underground installations. The integrated female thread offers compatibility with standard 1" male fittings, valves or adapters, enabling quick transitions between PE pipework and threaded components without additional transition pieces. The compact 90° design saves space in confined installations and facilitates neat routing of supply lines.

Suitable for

• Domestic and small commercial plumbing where PE piping needs to connect to threaded valves or fittings
• Irrigation systems including garden and agricultural water distribution
• Outdoor and underfloor installations requiring corrosion-resistant joints

Key specifications

• Material: polyethylene (PE) elbow body with a threaded female port
• PE socket size: 25 mm nominal for standard PE pipe insertion
• Thread type: female 1" compatible with standard male threads
• Configuration: 90° elbow for change of direction
• Application pressure range: suitable for water and low-pressure fluid systems
• Typical installation environment: indoor, outdoor and buried pipework

How to use

Prepare the PE pipe by cutting squarely and removing burrs, then insert the 25 mm PE pipe into the socket end following the manufacturer's guidance for fusion, electrofusion or mechanical joining method appropriate to the specific PE system. Thread the male component into the 1" female port by hand, then tighten with an appropriate wrench until secure, taking care not to overtighten plastic parts. Ensure seals or thread tape are applied if required by the connected component to prevent leaks. After installation, inspect the joint and perform a pressure test at the system's working pressure to confirm leak-free operation.

Usage recommendations

Use this fitting in systems designed for low to moderate pressure and follow the PE pipe joining methods recommended by the pipe manufacturer. Avoid exposure to aggressive solvents at the threaded connection and protect plastic threads from excessive mechanical stress or overtightening. For buried applications, follow local standards for bedding and backfill to prevent point loads on the fitting.
