Angle fitting Herz Kolano 20x2–Rp1/2 with internal thread P 7120 21

Herz Kolano 20x2–Rp1/2 with internal thread P 7120 21 is an angle fitting designed to connect a 20x2 mm tube to a Rp1/2 threaded component at a right angle. Intended for plumbing and heating installations, this compact fitting enables a change of direction while maintaining a sealed connection between a 20x2 pipe and standard Rp1/2 plumbing fittings. Its design is suitable for installations where space is limited and a reliable 90° transition is required.

Advantages

The fitting offers a compact right-angle connection that reduces the need for extended piping runs and simplifies layout in confined spaces. It provides a secure threaded interface on the Rp1/2 side while maintaining a consistent 20x2 tube connection, ensuring compatibility with common heating and plumbing materials. The part is produced by a manufacturer known for components for HVAC and plumbing systems, ensuring dimensional consistency and suitability for standard installation practices.

Suitable for

• Residential heating manifolds and radiator connections
• Domestic water supply lines with 20x2 tubing
• Commercial plumbing installations requiring compact 90° connections
• Retrofit projects where space constraints demand angled fittings

Key specifications

• Tube connection size: 20x2 mm
• Thread type: Rp1/2 internal (female) thread
• Function: 90° angle change between tube and threaded component
• Application area: plumbing and heating systems
• Installation orientation: right-angle connection suitable for tight spaces

How to use

Prepare the 20x2 tube end according to standard cutting and deburring procedures to ensure a clean, square face. Insert or attach the tube to the fitting following the manufacturer's recommended joining method for the specific material (compression, press, or soldering as applicable) and secure the threaded Rp1/2 connection to the mating component using appropriate thread sealant or tape where required by local codes. Verify alignment and tightness, then pressure-test the installation before putting the system into regular operation.

Usage recommendations

Use the fitting in systems with compatible 20x2 tubing and Rp1/2 threaded components; follow local plumbing and heating standards for sealing, torque, and pressure testing. Avoid excessive bending or mechanical stress at the joint and ensure accessible installation for future inspection and maintenance.
