Bronze Coupling SANHA 4270G GW 18 mm x 1/2" (SANHA 142701812)

The SANHA 4270G bronze coupling GW 18 mm x 1/2" is a threaded pipe fitting engineered to join 18 mm copper or compatible tubes with 1/2" threaded components. Manufactured from bronze, the coupling combines corrosion resistance and mechanical strength to deliver a reliable threaded connection in plumbing and heating systems. Its compact design and precise threading enable straightforward integration into repair work, extensions, and new installations where a durable metal-to-thread junction is required.

Advantages

Bronze construction offers enhanced resistance to corrosion compared with some other metals, ensuring longer service life in water and heating environments. The fitting’s thread form and dimensional accuracy facilitate leak-minimised connections with standard 1/2" threaded parts. Its compatibility with 18 mm tubes and common threaded components makes it a versatile solution for maintenance and system modification tasks. The solid metal body provides mechanical robustness under typical residential and commercial pressures.

Suitable for

• Connecting 18 mm copper or compatible tubes to 1/2" threaded valves, taps and appliances
• Plumbing repairs and replacement of worn threaded joints
• Heating system extensions where a threaded bronze coupling is required
• Applications requiring a corrosion-resistant metal threaded connector

Key specifications

• Material: bronze
• Connection A: 18 mm tube (for copper or compatible tubing)
• Connection B: 1/2" male/female threaded interface for standard plumbing components
• Application: potable water and heating systems, repair and extension work
• Form factor: compact threaded coupling suitable for inline installations

How to use

Prepare the 18 mm tube by cutting squarely and deburring the end to ensure a clean seating surface. Screw the coupling onto the 1/2" threaded component using appropriate thread sealant or PTFE tape as required by system specifications and local codes. Push the prepared 18 mm tube fully into the coupling and secure according to the connection method compatible with this model (ensure the pipe is correctly aligned before final tightening). After assembly, pressurise the system and inspect the joint for leaks; tighten further if permitted and needed.

Usage recommendations

Use compatible thread sealants and follow local plumbing regulations. Avoid over-tightening to prevent damage to threads and mating components. When working with potable water systems, ensure materials and installation methods meet applicable standards.
