SANHA Bronze Female Threaded Coupling 4270G GW 28 mm x 1"

SANHA Bronze Female Threaded Coupling 4270G GW 28 mm x 1" is a bronze muffa designed to join external-threaded pipes and fittings. The coupling provides a female threaded connection (GW) in a compact 28 mm x 1" size, suitable for plumbing, heating and potable water systems where a resilient metal connection is required. Constructed from bronze, the fitting offers inherent corrosion resistance and mechanical strength compared with many non-metal alternatives.

Advantages

The bronze construction ensures long-term resistance to corrosion and wear in water and heating applications. Its female threaded design allows secure connections to external-threaded components without soldering or press tools, enabling straightforward assembly and disassembly for maintenance. The coupling's dimensional compatibility with standard 28 mm and 1" threaded components facilitates integration into mixed-metal installations.

Suitable for

• Plumbing systems that require threaded metal connections
• Heating installations, including radiators and boiler connections
• Potable water applications where a durable bronze coupling is specified
• Repair and retrofit work on existing threaded pipe networks

Key specifications

• Material: Bronze
• Connection type: Female threaded coupling (GW)
• Nominal size: 28 mm x 1"
• Application media: Potable water, heating fluids
• Typical use: Mechanical threaded joint for pipes and fittings

How to use

Ensure mating external threads are clean, undamaged and match the 28 mm x 1" specification. Apply an appropriate thread sealant or PTFE tape rated for potable water and heating systems to the male thread if required by local practice. Screw the coupling onto the male thread by hand, then tighten with suitable wrenches until a secure, leak-free joint is achieved without over-torquing. Inspect the assembled joint under system pressure and re-tighten if necessary following the manufacturer’s torque guidance for bronze fittings.

Usage recommendations

Use in accordance with local plumbing and heating codes. Avoid exposing the bronze coupling to highly aggressive chemicals or environments not compatible with bronze. When joining dissimilar metals, consider appropriate measures to prevent galvanic corrosion, such as dielectric unions or compatible sealing materials.
