## Summary description

TECE brass transition coupling, size 20 mm × 1/2", designed for joining 20 mm pipework to a 1/2" threaded fitting. Made of solid brass for corrosion resistance and reliable mechanical strength. Suitable for potable water and general plumbing installations where pipe-to-thread transitions are required. Used in repair, replacement and new-build plumbing connections.

## Long description

TECE brass transition coupling 20 mm x 1/2" provides a compact, reliable solution for connecting 20 mm pipework to standard 1/2" threaded fittings. Manufactured from solid brass, the coupling is designed for plumbing applications where a secure pipe-to-thread transition is required. It is suitable for potable water installations and general plumbing systems, and is commonly used in repairs, replacements and new-build projects where compatibility between metric pipe sizes and imperial threaded components is needed.
Advantages
The solid brass construction offers corrosion resistance and mechanical durability for long service life in typical plumbing environments. Its precise threading and dimensional accuracy ensure a tight, leak-resistant connection when installed following standard plumbing practices. The coupling’s compact form factor allows installation in confined spaces and simplifies transitions between 20 mm piping and 1/2" threaded fixtures without additional adapters.
Suitable for
Connecting 20 mm plastic or metal pipes to 1/2" threaded fittings
Potable water supply lines in residential and commercial buildings
Repair or replacement of existing pipe-to-thread joints
New plumbing installations requiring metric-to-imperial transitions
Key specifications
Material: solid brass for corrosion resistance
Pipe side connection: 20 mm outer diameter
Threaded side: 1/2" standard male/female threaded fitting (imperial)
Application: potable water and general plumbing use
Design: compact transition coupling for pipe-to-thread connections
How to use
Prepare the 20 mm pipe by cutting squarely and deburring the end to ensure a smooth fit. Threaded fittings should be clean and free of old sealant or debris. Install the coupling by engaging the 1/2" thread to the mating component and tightening to the recommended torque for the fitting material; use appropriate sealing method (PTFE tape or approved pipe sealant) on the threaded side if required by local plumbing practice. Verify alignment and then test the joint under working pressure to confirm leak-tightness.
Usage recommendations
Use certified sealing materials and follow local plumbing codes. For installations exposed to aggressive environments or dissimilar metal contacts, consider appropriate measures such as dielectric fittings or additional corrosion protection. Periodically inspect connections during routine maintenance to ensure ongoing integrity.
