Angle fitting Herz Kolano 20x2–Rp3/4 with internal thread P 7120 22

Herz Kolano P 7120 22 is an angle fitting engineered for plumbing and heating installations. It provides a 90° change of direction with a 20x2 mm pipe connection on one side and an internal Rp3/4 threaded connection on the other, enabling a compact and reliable junction between a plain pipe end and a female-threaded component. The fitting is intended for use with compatible metal or multilayer pipes in domestic and light commercial systems where a threaded connection is required.

Advantages

The product offers a space-saving right-angle connection that simplifies routing of supply and return lines. Its combination of a 20x2 push or solder pipe interface and an internal Rp3/4 thread allows straightforward assembly with valves, radiators, and manifold elements that accept female threads. The design reduces the need for additional adapters and helps maintain hydraulic continuity and leak-resistant connections when installed according to recommended methods.

Suitable for

• Residential heating and hot water pipe runs where a 90° turn is required
• Connections to threaded valves, radiators, or manifolds with Rp3/4 female thread
• Domestic plumbing installations using metal or multilayer pipes with 20x2 dimensions
• Light commercial building services with similar pipe and thread standards

Key specifications

• Angle: 90° (right angle)
• Pipe connection size: 20x2 mm
• Thread type: internal Rp3/4 (female, parallel thread)
• Application: plumbing and heating installations
• Compatible pipe types: metal and multilayer pipes with 20x2 dimensions

How to use

Prepare the pipe end by cutting squarely, deburring, and cleaning before assembly. Fit the 20x2 pipe into the appropriate connection end according to the pipe system requirements (compression, press, or soldering method as applicable), and apply suitable sealing measures for the Rp3/4 internal thread such as PTFE tape or approved thread sealant when connecting the mating external thread. Tighten threaded connections to the torque recommended by the mating component manufacturer to avoid overtightening. After installation, pressurize and test the system for leaks following local standards and codes.

Usage recommendations

Use only with pipes and fittings rated for the system's maximum operating temperature and pressure. Ensure thread sealing materials are compatible with potable water if used on domestic hot water systems. Avoid exposing the fitting to aggressive chemicals or environments that could affect the material properties; follow industry best practices for installation and maintenance.
