Fitting elbow Detal-met Kolano PP 20 mm with female thread 1/2"

Detal-met Kolano PP 20 mm with female thread 1/2" is a 90° elbow fitting made of polypropylene (PP) designed for use in plumbing and heating systems. It provides a transition between a 20 mm plastic pipe and an internal 1/2" threaded connection, allowing connection to valves, taps or other threaded fixtures. The fitting is intended for potable water and general utility lines where a reliable plastic-to-thread joint is required.

Advantages

The polypropylene construction ensures chemical resistance and corrosion-free performance in water systems. Its 90° geometry enables compact directional changes in pipe runs while maintaining flow characteristics appropriate for small-diameter systems. The integrated female thread simplifies installation to threaded components without the need for additional adapters, and the lightweight design reduces mechanical load on the piping layout.

Suitable for

• Domestic potable water supply lines with 20 mm plastic pipe
• Heating circuits and secondary loops requiring threaded connections
• Connection of 20 mm pipework to threaded valves, taps, or fittings
• Repair or modification of existing installations that use 1/2" threaded fixtures

Key specifications

• Material: polypropylene (PP)
• Pipe connection size: 20 mm
• Thread type: internal (female) 1/2"
• Angle: 90° elbow
• Application: potable water and general utility lines

How to use

Prepare the 20 mm plastic pipe end by cutting it square and deburring to ensure a clean fit. Join the pipe to the fitting following the manufacturer's recommended method for the specific 20 mm system (e.g., push-fit, solvent welding, or mechanical compression) compatible with polypropylene. Apply an appropriate thread sealant or PTFE tape to the external 1/2" male thread of the mating component, then screw the component into the fitting's internal thread until hand-tight; complete final tightening using appropriate tools without over-torquing to avoid thread or fitting damage. Verify alignment and test the assembled joint for leaks before putting the system into regular service.

Usage recommendations

Use compatible installation techniques and materials for polypropylene fittings and 20 mm pipe systems. Avoid excessive mechanical stress or bending near the joint, and follow local plumbing codes and pressure/temperature limits applicable to plastic fittings. When connecting to metal components, ensure thread sealing is applied correctly and inspect joints after initial pressurization.
