Plastic elbow 90° AKA Kolano J-71 63 mm socket 2" for PE pipe

AKA Kolano J-71 is a 90° polyethylene (PE) elbow with a 63 mm (2") socket connection designed for PE pipe systems. The fitting enables a right-angle change of direction in water supply or drainage installations and is intended for creating secure socket joints between polyethylene pipes. Manufactured for compatibility with standard PE pipe dimensions, this elbow is suitable for use in domestic and light commercial plumbing where PE piping is specified.

Advantages

The polyethylene construction provides corrosion resistance and long service life in contact with potable water and non-aggressive fluids. The socket design ensures a simplified joint using compatible PE welding or socket assembly methods and reduces the need for complex mechanical couplings. The compact 90° form factor allows straightforward route changes in tight installation spaces while maintaining hydraulic flow characteristics appropriate for 63 mm PE piping.

Suitable for

• Changing direction in PE water supply lines
• Drainage systems using polyethylene pipes
• Domestic plumbing installations and garden irrigation
• Light commercial plumbing where PE piping is specified

Key specifications

• Material: polyethylene (PE)
• Angle: 90° elbow
• Connection type: socket for insertion/welding
• Socket diameter: 63 mm (2") suitable for corresponding PE pipe
• Application: water supply and drainage with non-aggressive media

How to use

Prepare pipe ends by cutting square and cleaning to remove dirt and burrs. Align the PE pipe with the socket and perform the appropriate joint method for PE fittings (electrofusion, butt fusion or compatible socket welding) following the equipment manufacturer's instructions and local plumbing standards. Ensure proper heating and cooling cycles where thermal fusion is used, and verify joint integrity by pressure testing the system after cooling. Use appropriate supports and avoid mechanical stresses at the joint during installation.

Usage recommendations

Verify material compatibility and operating pressure ratings for the complete system prior to installation. Follow local regulations for potable water or drainage installations and use qualified personnel for fusion welding or socket assembly to ensure leak-free, durable joints.
