Corner elbow adapter Detal-met Kolano PP 20 mm GZ 1/2" fitting

Detal-met Kolano PP 20 mm GZ 1/2" fitting is a polypropylene elbow designed to change the direction of plastic piping and provide a threaded connection to fixtures or valves. The fitting combines a 20 mm socket for insertion of PP or compatible plastic pipe with a GZ 1/2" male threaded end to attach to standard threaded components. It is intended for domestic plumbing systems and potable water installations where polypropylene fittings are specified.

Advantages

The polypropylene construction provides chemical resistance and low weight while maintaining dimensional stability for secure joints. The integrated 20 mm socket simplifies pipe insertion and heat fusion or mechanical connection methods typical for PP piping. The GZ 1/2" threaded end enables direct connection to metal or plastic threaded valves, taps, and fittings without additional adapters. Its design reduces the need for complex assemblies when changing pipe direction and transitioning to threaded components.

Suitable for

• Domestic potable water plumbing where PP fittings are required
• Changing pipe direction in residential supply networks
• Connecting PP piping to threaded valves, taps, or fixtures
• General household plumbing repairs and installations

Key specifications

• Material: polypropylene (PP)
• Socket (pipe connection) diameter: 20 mm
• Threaded end: male GZ 1/2" (standard pipe thread)
• Type: 90° elbow (corner) fitting
• Intended use: potable water and general domestic plumbing

How to use

Prepare the 20 mm PP pipe by cutting squarely and deburring the end before insertion into the socket. Join the pipe to the socket using the appropriate method for the PP system in use (e.g., socket fusion, electrofusion, or a compatible mechanical coupling) following manufacturer and local plumbing regulations. Apply suitable sealing tape or sealant to the male GZ 1/2" thread before tightening to a matching female threaded component. Ensure all connections are properly aligned and tightened to avoid strain on the joint, then pressure-test the system according to local codes.

Usage recommendations

Use the fitting only within the temperature and pressure limits specified for polypropylene plumbing systems and follow local installation standards. Do not overtighten the threaded connection; use appropriate sealing material and hand-then-wrench tightening to avoid damaging threads. For potable water installations, ensure compatibility of joining methods and any sealants with drinking water regulations.
