AKA 90° PE Elbow J-71 20 mm to 1/2" Female Thread (PE-58-120)

AKA 90° PE Elbow J-71 20 mm to 1/2" Female Thread is a compact right-angle fitting that connects 20 mm polyethylene (PE) pipe to a 1/2" female threaded outlet. Manufactured for use in potable water supply and irrigation installations, this elbow provides a mixed connection between PE tubing and threaded valves or fittings while minimizing space requirements at pipe turns. The design ensures a stable transition from PE pipe to standard threaded components at a 90° angle.

Advantages

The fitting combines a PE pipe connection with a standard 1/2" female thread, enabling direct mating with threaded valves and accessories without additional adapters. Its right-angle configuration reduces installation footprint in tight spaces and helps route piping neatly. Constructed for corrosion resistance and compatibility with common water systems, the elbow supports reliable mechanical connection to PE tubing and maintains flow characteristics appropriate for domestic and light commercial applications.

Suitable for

• Domestic water supply lines that use 20 mm PE pipe
• Irrigation systems and garden watering installations
• Connections to threaded valves, taps, or fittings with 1/2" female threads
• Installation points with limited space requiring a 90° turn

Key specifications

• Elbow angle: 90°
• PE pipe connection nominal diameter: 20 mm
• Thread type: 1/2" female
• Material: polyethylene (PE) body with threaded outlet suitable for metal/plastic threaded fittings
• Typical applications: potable water distribution, irrigation and general plumbing

How to use

Prepare the 20 mm PE pipe by cutting squarely and deburring the end. Insert the pipe into the PE connection portion of the elbow to the recommended insertion depth and secure according to the PE joining method appropriate for the fitting (mechanical compression, electrofusion, or other compatible system if applicable). Attach the 1/2" female threaded outlet to the corresponding male thread of a valve or fitting, using suitable thread sealant or tape as required for the system and medium. Check for alignment and ensure the elbow is properly seated to prevent leaks at both connections.

Usage recommendations

Use this elbow in systems designed for cold or ambient-temperature water; consult local standards for pressure ratings and approved joining methods. Verify compatibility of the threaded mating component material to avoid galvanic issues and apply appropriate thread sealing. Regularly inspect connections after installation and before initial pressurization.
