Angle Elbow Connector Detal-met Kolano PP 20 mm GZ 3/4" - plastic pipe fitting, male threaded 3/4"

Detal-met Kolano PP 20 mm GZ 3/4" is a polypropylene 90° angle elbow designed to join a 20 mm plastic pipe to a male 3/4" threaded connection. The fitting combines a smooth 20 mm socket for push-fit or glued plastic pipe installation with a male threaded end to connect to valves, fixtures or threaded components. Its compact right-angle shape enables direction changes in confined spaces while delivering a corrosion-resistant, chemically stable joint suitable for potable water and heating systems in residential and light commercial use.

Advantages

The polypropylene construction ensures chemical resistance and long-term dimensional stability, reducing risk of corrosion and scale compared with metal fittings. The integrated male 3/4" thread provides reliable mechanical connection to threaded valves and devices, while the 20 mm socket gives a secure interface for standard plastic piping. Its compact 90° design minimises space requirements and simplifies routing of pipework in tight installations.

Suitable for (tasks / use cases)

• Connecting 20 mm plastic pipe to valves, taps or threaded fixtures
• Creating a compact 90° change of direction in water supply lines
• Domestic potable water installations and small heating circuits
• Repair or retrofit works where transition from plastic pipe to threaded components is required

Key specifications

• Material: polypropylene (PP)
• Pipe socket diameter: 20 mm for plastic pipe connection
• Thread type: male threaded end 3/4"
• Angle: 90° elbow
• Typical applications: water supply and heating systems

How to use

Prepare the 20 mm plastic pipe by cutting squarely and deburring the end. Depending on the pipe system, insert the pipe into the 20 mm socket using the appropriate joining method for polypropylene fittings (push-fit, solvent welding or adhesive indicated for PP). Apply thread sealant tape or an approved sealing compound to the male 3/4" thread before connecting to the mating female threaded component. Tighten by hand and finish with a wrench until secure, avoiding over-tightening to prevent deformation of the plastic thread. Verify alignment and test the installed joint under system pressure according to local codes.

Usage recommendations

Use compatible pipe joining methods and approved sealants for polypropylene and follow local plumbing regulations. Avoid exposing the fitting to prolonged direct sunlight or temperatures beyond the material's rated range. When connecting to metal components, ensure proper sealing and do not overtighten to prevent thread damage.
