Compression elbow Detal-met Kolano PP 20 mm with female thread 3/4"

Detal-met Kolano PP 20 mm is a polypropylene compression elbow with a 3/4" female threaded connection designed to change the direction of a pipe by 90°. The fitting enables a secure junction between 20 mm plastic pipes and components with a 3/4" male thread, such as valves, taps or other fittings commonly used in domestic and light commercial plumbing and heating systems. Constructed from polypropylene, the elbow offers corrosion resistance and chemical inertness suitable for potable water distribution and closed heating circuits.

Advantages

The compression design allows installation without soldering or specialized tooling, providing a reliable seal on 20 mm plastic pipes. The polypropylene material is resistant to scale and most chemicals found in water systems and reduces the risk of galvanic corrosion compared with metal fittings. The integrated 3/4" female thread provides compatibility with common threaded valves and adapters, simplifying connections and maintenance. The compact 90° form factor saves space in tight installations.

Suitable for

• Connecting 20 mm plastic pipes to valves or fittings with a 3/4" male thread
• Domestic cold and hot water distribution systems
• Radiator and underfloor heating manifolds in light commercial and residential buildings
• Repair and retrofit jobs where a threaded interface is required

Key specifications

• Material: polypropylene (PP)
• Pipe connection: compression for 20 mm plastic pipe
• Thread type: female threaded connection sized to accept 3/4" male threads
• Angle: 90° elbow
• Typical applications: potable water distribution, heating circuits, plumbing connections

How to use

Prepare the 20 mm plastic pipe by cutting it square and ensuring the outer surface is clean and free of burrs. Slide the compression nut and any supplied sealing components onto the pipe, insert the pipe fully into the elbow body until it seats, then tighten the compression nut by hand and finish with a wrench if necessary, taking care not to overtighten. Screw the 3/4" male threaded component into the female thread until hand-tight, then apply a further small turn with an appropriate wrench to ensure a leak-free connection. Follow local plumbing codes and the instructions of any mating components when installing.

Usage recommendations

Use only with compatible 20 mm plastic pipes intended for compression fittings and with standard 3/4" male threaded components. Do not overtighten threaded connections or compression nuts to avoid damaging threads or deforming the plastic body. For installations carrying hot water or under pressure, verify temperature and pressure ratings of the overall system and perform a pressure test after installation.
