## Summary description

T-piece (T-fitting) B\_METERS TT-20 designed for mounting a temperature sensor. The brass T-fitting has 3/4" threaded connections and provides a dedicated branch for inserting a temperature probe into a heating or plumbing line. Suitable for integration with temperature sensors in residential and commercial hydronic systems to measure fluid temperature without interrupting flow.

## Long description

B\_METERS temperature sensor T-piece TT-20 is a brass T-fitting with 3/4" threaded connections designed to provide a dedicated branch for mounting a temperature probe into a heating or plumbing line. The fitting enables insertion of a temperature sensor into a running hydronic circuit without interrupting fluid flow, allowing accurate measurement of fluid temperature in residential and commercial installations. Its compact design and standard thread sizes make it compatible with common temperature probes and piping systems.
Advantages
The brass construction offers good corrosion resistance and mechanical strength for long-term use in potable water and heating systems. The 3/4" threaded connections ensure secure attachment to existing piping and fittings, while the dedicated branch provides a stable mounting point for the temperature probe that minimizes flow disturbance. The T-piece is suitable for retrofitting or new installations and supports reliable temperature measurement in circulating systems.
Suitable for
Integration of temperature sensors into heating systems (boilers, radiators, underfloor heating)
Measurement of fluid temperature in plumbing and domestic hot water circuits
Retrofit installations where sensor insertion is required without shutting down the circuit
Commercial hydronic systems requiring temperature monitoring
Key specifications
Material: brass
Connection type: threaded T-fitting
Thread size: 3/4" for main line and sensor branch
Purpose: dedicated branch for temperature probe insertion
Compatibility: suitable for common hydronic and plumbing temperature sensors and probes
How to use
Install the T-piece in the piping run at the location where fluid temperature measurement is required, using appropriate sealing materials on the threads to prevent leaks. Mount the temperature probe into the dedicated branch and tighten securely according to the probe manufacturer's instructions. Ensure the fitting orientation allows correct probe immersion and that the system is pressure-tested after installation. If required, isolate and drain the circuit section before fitting to meet local installation practices and safety standards.
Usage recommendations
Use compatible temperature probes sized for 3/4" fittings and follow sensor manufacturer guidance for insertion depth and sealing. Where applicable, install the T-piece in a straight section of pipe to ensure representative temperature readings and avoid placing the sensor immediately adjacent to mixing points or components causing local temperature variation.
