Unidelta elbow PE GZ 50 mm x 2" (threaded male) — plumbing fitting, model 602551

Unidelta elbow PE GZ 50 mm x 2" (model 602551) is a polyethylene 90° plumbing fitting that connects a 50 mm PE socket end to a 2" male threaded (GZ) outlet. It is intended for changing the direction of water and fluid distribution in supply, irrigation and general utility pipelines where a transition from PE pipe to a threaded component is required. The fitting combines the corrosion resistance and flexibility of PE with a standardized threaded male connection for compatibility with valves, adapters and other threaded devices.

Advantages

The PE construction ensures chemical and corrosion resistance and reduces weight compared with metal alternatives. The compact 90° design saves installation space and provides a reliable directional change between a butt-fused or socketed PE pipeline and a 2" threaded component. The male threaded end follows common G (BSP) thread form for compatibility with many valves and fittings, while the socket end is sized for secure connection to 50 mm PE pipe. The product requires minimal maintenance and is suitable for use in systems conveying potable water, irrigation water and many non-aggressive fluids.

Suitable for

• Connecting 50 mm PE pipelines to 2" threaded valves or adapters
• Direction changes in water supply and irrigation systems
• Utility and service pipelines requiring a threaded transition point

Key specifications

• Material: polyethylene (PE)
• Elbow angle: 90°
• Socket end nominal diameter: 50 mm
• Threaded end: 2" male (GZ) — standard pipe thread form
• Application: water and non-aggressive fluid distribution systems

How to use

Select a compatible 50 mm PE pipe and prepare the pipe end according to PE joining recommendations (cut square, remove burrs). Install the socket end by appropriate fusion or mechanical socket method specified for the pipe system. Tighten the 2" male threaded connection to the mating component using suitable thread sealant or tape where required by the installation practice. Verify alignment and support the pipeline to avoid undue stress on the joint. Follow local codes and manufacturer guidelines for pressure ratings and joining procedures.

Usage recommendations

Use this elbow where a transition between PE pipework and standard 2" threaded components is needed. Ensure thread compatibility (G/BSP) with the mating part and apply an appropriate tape or sealant if a leak-tight threaded joint is required. Avoid exposure to aggressive chemicals outside typical potable and irrigation water types and protect the fitting from sustained mechanical loads or UV exposure when used outdoors.
