Bronze Coupling SANHA 4270G GW 15 mm x 1/2" (142701512)

The SANHA bronze coupling 4270G GW 15 mm x 1/2" is a threaded pipe fitting designed for connecting 15 mm tubing to components with a 1/2" external thread. Constructed from bronze, this coupling offers corrosion resistance and mechanical stability suitable for water, heating and general plumbing applications. It is intended for use where a reliable threaded joint between copper, brass or other compatible metal fittings is required.

Advantages

The bronze material provides improved resistance to corrosion and dezincification compared with some other alloys, supporting long service life in potable water and heating systems. The threaded design enables a secure, leak-minimizing connection that can be disassembled for maintenance or reconfiguration. Its compact size and standard thread form make it compatible with commonly used 15 mm tubing and 1/2" threaded components in residential and light commercial installations.

Suitable for

• Joining 15 mm copper or metal tubing to 1/2" threaded valves, fittings or appliances
• Domestic plumbing and potable water systems
• Central heating circuits and radiator connections
• Repair and maintenance of metal piping networks

Key specifications

• Material: bronze
• Connection types: 15 mm tubing to 1/2" external/internal threaded component
• Application medium: potable water, heating fluids
• Suitable connection metals: copper, brass and compatible metals
• Typical environments: residential and commercial plumbing/heating systems

How to use

Ensure both the 15 mm tubing and the mating 1/2" threaded component are clean and free from debris. Prepare the tubing end according to the system requirements (cut square, deburr, and, if applicable, insert any required sleeve or insert). Apply appropriate thread sealant or PTFE tape to the male thread following manufacturer guidance, then hand-start the coupling onto the thread and tighten with a suitable wrench until a secure, leak-free joint is achieved. After assembly, pressure-test the connection in accordance with local regulations and project specifications.

Usage recommendations

Use compatible thread sealants approved for potable water systems when connecting to drinking-water pipelines. Avoid overtightening to prevent damage to threads or deformation of the coupling; follow standard torque practice for bronze fittings. Inspect joints periodically for signs of leakage or corrosion as part of routine system maintenance.
