Brass female coupling SANHA 4270G GW 15 mm × 3/8" (142701538)

SANHA 4270G GW 15 mm × 3/8" is a brass (bronze) female coupling designed to connect a 15 mm pipe or fitting to a 3/8" male threaded component. The coupling provides a threaded transition between metric copper or multilayer piping and imperial threaded fittings, valves or instruments. Made of brass/bronze, it is suitable for plumbing and heating systems where a corrosion-resistant, mechanically stable joint is required.

Advantages

The brass construction offers good corrosion resistance and mechanical strength for standard domestic and commercial plumbing applications. Internal threading provides a reliable sealed connection to 3/8" male threads without the need for soldering. Compact dimensions and a standardized connection interface make the coupling easy to integrate into mixed-dimension installations and to replace or service individual components.

Suitable for

• Connecting 15 mm copper or multilayer pipes to 3/8" threaded valves or fittings
• Domestic and commercial heating systems
• Piping assemblies for water supply and distribution
• Retrofit and repair work where metric-to-imperial conversion is required

Key specifications

• Material: brass/bronze
• Connection type: female internal thread to 3/8"
• Pipe size side: 15 mm outer dimension
• Thread standard: compatible with standard 3/8" male threads
• Application: potable water, heating and general plumbing

How to use

Prepare the 15 mm pipe end according to the piping system type: cut square, deburr and, if applicable, slide on any required compression or press components. Ensure the mating 3/8" male thread is clean and undamaged. Apply an appropriate thread sealant or tape to the male thread if required by the installation practice, then screw the female coupling onto the male thread by hand and tighten with a suitable wrench to the recommended torque for the materials involved. After assembly, check the connection for leaks under operating pressure and adjust as necessary.

Usage recommendations

Use compatible sealing materials rated for potable water where applicable. Avoid over-tightening to prevent thread damage and verify chemical compatibility if used in non-potable or aggressive environments.
