## Long description

VIEGA transitional coupling 15 mm x 1/2" brown model 102128 is a pipe fitting designed to connect a 15 mm copper or plastic pipe to a 1/2" threaded fitting. The coupling features a brown finish and a design intended to provide a fluid-tight transition between pipe and threaded fixture in plumbing and heating systems. It is intended for repairs, installations and retrofits where a secure, soldered transition is required.
Advantages
The coupling provides a soldered connection and a threaded end with a conical sealing profile to ensure a watertight joint. Its construction combines a nozzle suitable for connection to pipe with a threaded interface compatible with standard 1/2" fittings. The product is specified for plumbing and heating use and is finished in brown to match visible installations.
Suitable for
Connecting 15 mm copper or plastic pipe to 1/2" threaded fittings
Plumbing repair and replacement tasks
Heating system connections and retrofits
Applications requiring a soldered pipe connection with a threaded outlet
When it may not be suitable
This transitional coupling is not suitable for gas installations. It is intended for liquid plumbing and heating systems only. Do not use the fitting where a different thread type, size, or a gas-certified component is required.
Key specifications
Connection sizes: 15 mm (pipe) to 1/2" (threaded fitting)
Thread type: R-thread with conical sealing
Pipe-side connection: soldered joint
Material notes: brass nozzle with gunmetal or silicon bronze threaded connection (as specified by manufacturer)
Finish: brown
Intended media: liquids in plumbing and heating systems (not for gas)
How to use
Prepare the 15 mm pipe end by cutting square and cleaning the surface for soldering. Fit the coupling onto the pipe and perform a proper soldering procedure according to plumbing standards to create the soldered joint. On the threaded side, apply an appropriate thread sealant or tape for tapered R-threads if required, then tighten the coupling to the receiving 1/2" fitting until the conical sealing surfaces engage and form a leak-tight connection. Follow applicable local installation codes and safety practices during installation.
What to consider before purchase
Verify that 15 mm pipe and 1/2" R-thread are the correct sizes for your installation
Confirm that the installation is liquid plumbing or heating (product is not for gas)
Ensure you have soldering tools and materials or a qualified installer for the soldered joint
Check compatibility of finish and material with surrounding components and system requirements
Usage recommendations
Use the coupling only in accordance with manufacturer instructions and local regulations. Ensure proper surface preparation and soldering technique for a durable joint, and use suitable thread sealant on the threaded side for reliable sealing. Do not use for gas installations.
