Plastic elbow 90° AKA Kolano J-64 40 mm PE (model PE-56-040)

AKA Kolano J-64 40 mm PE is a 90° plastic elbow manufactured from polyethylene for connecting and redirecting 40 mm pipes. The fitting is designed for use in irrigation, drainage and low-pressure water systems, providing a compact, corrosion‑resistant joint that simplifies changes of direction in piping runs. Its smooth internal surface supports unobstructed flow while the external shape allows straightforward assembly in confined spaces.

Advantages

The polyethylene construction offers chemical resistance and protection against corrosion and environmental degradation. The 90° geometry enables tight directional changes without additional pipe length or complex coupling assemblies. Lightweight and dimensionally stable, the elbow is easy to handle and install, and its uniform wall thickness ensures consistent performance under the pressures typical for low‑pressure water and irrigation systems.

Suitable for

• Irrigation systems for gardens, allotments and small agricultural plots
• Drainage lines and stormwater routing in domestic installations
• Low‑pressure water distribution and piping rerouting
• Temporary or permanent outdoor waterworks where corrosion resistance is required

Key specifications

• Material: polyethylene (PE)
• Connection type: socket/end for 40 mm pipe
• Angle: 90 degrees
• Application pressure class: suitable for low‑pressure systems (irrigation/drainage)
• Corrosion resistance: inherent to PE material
• Typical use environment: outdoor and underground non‑pressurized to low‑pressure installations

How to use

Before installation, verify that the 40 mm pipe ends are clean, cut squarely and free from burrs. Align the pipe into the fitting socket until fully seated to ensure a secure connection; use the appropriate joining method for PE fittings (mechanical coupling, solvent/heat fusion or as specified by the system designer). Ensure that the assembled joint is supported and that shear or bending loads on the connection are minimized. For buried applications, backfill evenly and avoid concentrated loads directly over the fitting.

Usage recommendations

Use the elbow in systems within the manufacturer’s recommended pressure and temperature ranges for polyethylene components. For permanent installations consider fusion welding methods where compatible to achieve leak‑proof joints; for temporary or modular layouts use compatible mechanical couplers and support clamps. Regularly inspect exposed fittings for UV degradation if long‑term sunlight exposure is expected and protect with suitable covers or backfill.
