## Long description

TECE transition nipple in brass with an external 3/4" thread and a 20 mm connection diameter. This fitting is intended for connecting a 20 mm pipe to a 3/4" threaded component in potable water and heating installations. Manufactured from brass for corrosion resistance and mechanical strength, the component provides a stable metallic transition suitable for installation and repair tasks in plumbing systems.
Advantages
The brass construction offers good corrosion resistance and long-term dimensional stability under typical domestic water and heating system conditions. The external 3/4" thread enables direct connection to standard threaded fittings while the 20 mm connection provides compatibility with common copper or plastic pipework. The compact design simplifies installation in confined spaces and supports reliable sealing when used with appropriate sealing materials.
Suitable for
Connecting 20 mm pipelines to 3/4" threaded valves or fittings
Domestic potable water supply systems
Heating circuits and radiators requiring a threaded metallic transition
Plumbing repairs and retrofit installations
Key specifications
Material: brass
Connection A: 20 mm pipe connection
Connection B: external 3/4" threaded connection
Application: potable water and heating systems
Design: compact transition nipple for inline connections
How to use
Prepare the pipe end and threaded fitting surfaces by cleaning off debris and ensuring they are free of damage. If required, apply an appropriate thread sealant or PTFE tape to the external thread to ensure leak-tightness according to local installation practices. Insert the 20 mm pipe into the connection side as required by the pipe type (push-fit, soldering, or compression depending on system) and tighten the nipple into the 3/4" threaded fitting using a suitable wrench. Check alignment and ensure connections are secure but avoid over-tightening to prevent thread or component damage.
Usage recommendations
Use only materials and sealing methods compatible with potable water systems when installing in drinking water applications. Verify system pressure and temperature limits of surrounding components and follow local plumbing codes during installation.
