Plastic elbow fitting 45° 20 mm Detal-met Kolano PP 45° 20mm

Detal-met Kolano PP 45° 20mm is a polypropylene elbow fitting with a 45-degree angle and a 20 mm nominal diameter. It is intended for joining and redirecting plastic piping within plumbing and fluid systems. The fitting is compatible with PP piping and designed for applications such as potable water distribution, heating circuits, and general plumbing installations that use 20 mm polypropylene pipe.

Advantages

The polypropylene construction provides chemical resistance and low weight while maintaining dimensional stability under normal operating temperatures. The 45° angle enables smoother directional changes than a 90° bend, reducing flow resistance and stress on pipeline joints. Its compact size and standardized nominal diameter make it easy to integrate into existing 20 mm PP piping layouts.

Suitable for

• Residential potable water supply with 20 mm PP pipes
• Heating circuits and radiator connections using polypropylene piping
• Small-diameter plumbing runs and branch lines
• Repair or modification of existing 20 mm PP pipe systems

Key specifications

• Material: polypropylene (PP)
• Angle: 45 degrees
• Nominal diameter: 20 mm
• Connection type: socket-fitting for 20 mm PP pipe (compatible with standard PP joining methods)
• Typical applications: cold and hot water systems, heating circuits, general plumbing

How to use

Prepare pipe ends by cutting squarely and deburring to ensure full insertion. Fit the 20 mm PP pipe into the elbow socket to the required depth. Depending on the installation method used in the system, secure joints using the manufacturer-recommended technique for PP fittings—commonly solvent welding, heat fusion, or compatible mechanical connection methods. Verify alignment and ensure connections are clean and free of contaminants before pressure testing the system according to local codes.

Usage recommendations

When installing the Detal-met 45° elbow, follow applicable plumbing standards and the chosen PP joining method’s instructions. Avoid excessive mechanical stress on the joint during installation, and perform pressure and leak tests after assembly. Use fittings rated for the system’s maximum temperature and pressure.
