Tee fitting Herz P 7220 41 | 20x2–1/2–20x2 with female thread

Herz P 7220 41 is a tee fitting engineered for plumbing and heating installations, connecting a 20x2 copper or similar pipe to a 1/2-inch female threaded branch and a second 20x2 outlet. The fitting provides a threaded internal connection suitable for attaching valves, gauges, or appliances while maintaining a continuous 20x2 line. Designed for potable water and heating systems, the component is intended for applications that require a reliable branch with female thread integration.

Advantages

The tee fitting offers a compact solution for creating a threaded branch without interrupting the main 20x2 pipeline. Its female thread enables direct connection of standard 1/2-inch threaded components, reducing the need for additional adapters. The design supports use in drinking water and heating circuits and simplifies installation where a mixed pipe-to-thread transition is required.

Suitable for

• Branching a 20x2 supply or return line to a 1/2" threaded valve or fitting
• Integrating gauges, sensors or small appliances into potable water systems
• Creating threaded take-offs in heating circuit manifolds and distribution lines
• Retrofit work where a threaded connection is added to an existing 20x2 pipe run

Key specifications

• Pipe connection sizes: 20x2 — 20x2 with a 1/2-inch female threaded branch
• Thread type: internal 1/2-inch female thread for mating with standard 1/2" fittings
• Application: potable water systems and heating installations
• Material compatibility: intended for use with 20x2 metal piping such as copper or compatible alloys
• Function: tee fitting for branching and thread integration

How to use

Prepare the 20x2 pipe ends by cutting square and deburring. Insert and join the 20x2 connections according to the pipe and fitting joining method specified for the material (e.g., soldering, press-fit, or mechanical joint) and ensure correct alignment of the threaded branch. Apply an appropriate thread sealant or tape to the male 1/2-inch thread of the component to be connected and engage it into the female branch until secure. Verify all joints for tightness and perform a pressure test in accordance with system requirements.

Usage recommendations

Use the fitting in systems designed for potable water or heating. Select joining methods and thread sealants compatible with the pipe material and operating temperature and pressure. Inspect and test the assembly after installation for leaks and ensure that connected valves or devices are suitable for the system’s pressure rating.
