Elbow 90° AKA PE J-64 25 mm (PE-56-025) for polyethylene piping

AKA PE J-64 90° elbow, 25 mm (PE-56-025) is a polyethylene fitting designed to change the direction of a pipeline by 90°. It is intended for connecting polyethylene pipes with a matching outer diameter, providing a sealed and durable joint suitable for low-pressure water supply, irrigation and similar fluid distribution systems. The fitting is manufactured from polyethylene material compatible with standard PE piping and is sized for 25 mm lines.

Advantages

The 90° elbow offers a compact solution for changing pipe direction while maintaining hydraulic integrity and leak resistance. Made from polyethylene, the fitting provides chemical resistance, corrosion-free operation and long-term dimensional stability in typical water and irrigation applications. Its standardized dimensions ensure compatibility with PE piping of corresponding outer diameter and allow straightforward installation using standard joining methods for polyethylene systems.

Suitable for

• Low-pressure water supply lines
• Irrigation systems for gardens and small agricultural plots
• Underground or above-ground polyethylene pipe routing where a 90° turn is required
• Temporary or permanent fluid distribution networks using PE pipes

Key specifications

• Material: polyethylene (PE)
• Angle: 90 degrees
• Nominal size: for 25 mm outer diameter pipes
• Connection type: butt/compatible with standard PE joining methods
• Typical application pressure: low-pressure systems (refer to system design limits)

How to use

Select the elbow matching the outer diameter of the polyethylene pipes in the system. Prepare the pipe ends according to the chosen joining method (e.g., butt fusion, electrofusion or suitable mechanical connectors), ensuring clean, square cuts and removal of debris. Align the pipes and the elbow to achieve a true 90° change in direction, then perform the joining procedure recommended for polyethylene fittings and the specific connection type selected. Allow any fused or assembled joints to cool and cure as specified before pressurizing the system.

Usage recommendations

Verify compatibility of joining method and material before installation, follow applicable local standards for polyethylene pipeline assembly, and ensure operating pressures and temperatures remain within the limits of the PE piping system to maintain seal integrity and service life.
