Unidelta plumbing elbow Kolano PE GZ 40 mm x 1" — threaded male elbow for pipe connection

Unidelta Kolano PE GZ 40 mm x 1" is a threaded male elbow designed to join 40 mm polyethylene (PE) pipe to components with a 1" female thread. The fitting creates a 90° change of direction and provides a sealed threaded transition between PE piping and metal or plastic threaded fittings. It is intended for potable water distribution, garden irrigation lines and general service connections where a reliable PE-to-thread connection is needed.

Advantages

The elbow combines a polyethylene pipe connection with a standard 1" male thread, enabling a compact and leak-resistant angle connection without the need for additional adapters. Its design ensures a smooth 90° flow change and a secure mechanical joint when assembled according to manufacturer guidance. The component is compatible with commonly used PE pipework and threaded fittings, offering a straightforward solution for retrofits or new installations in domestic and light commercial systems.

Suitable for

• Household cold water supply lines using 40 mm PE pipe
• Garden and agricultural irrigation systems
• Service connections between PE mains and threaded valves or devices
• Repair or modification of existing PE pipe runs needing a threaded interface

Key specifications

• Pipe connection diameter: 40 mm for polyethylene (PE) pipe
• Thread type and size: external (male) 1" standard thread for mating with 1" female fittings
• Angle: 90° elbow
• Material compatibility: designed for use with PE pipe and standard threaded fittings made of metal or plastic
• Application: potable water, irrigation and general service connections

How to use

Prepare the 40 mm PE pipe by cutting a clean, square end and removing any burrs. Insert the pipe into the PE side of the elbow and secure according to the connection method compatible with the fitting (for example, electrofusion, mechanical compression or a push-fit variant if applicable). Apply appropriate sealing tape or sealant to the 1" male thread if required by the mating component, then hand-tighten and finish with a suitable wrench to achieve a leak-free threaded joint. Follow local plumbing codes and the installation instructions of all system components.

Usage recommendations

Inspect all mating surfaces before assembly and use compatible seals for potable water applications. Do not overtighten threaded joints to avoid thread damage; tighten to the torque recommended for the mating fitting. For buried or exposed external installations, confirm material compatibility and protection requirements for long-term service.
