SANHA brass female threaded coupling 4270G GW 28 mm x 5/4"

SANHA brass female threaded coupling 4270G GW 28 mm x 5/4" is a metallic coupling designed to join pipes or fittings with compatible male threads. Made of brass (bronze), the coupling provides a corrosion-resistant mechanical connection suitable for plumbing systems, heating circuits and potable water installations where a threaded joint is required. Its dimensions — 28 mm to 5/4" internal thread — allow transition between metric and imperial thread sizes in mixed-technology installations.

Advantages

The brass construction ensures durability and good resistance to corrosion in typical domestic and commercial water systems. A female threaded GW connection offers a reliable, reusable joint that can be tightened or disassembled for maintenance. The compact, simple design facilitates installation in confined spaces and supports standard sealing methods such as PTFE tape or thread sealant to ensure leak-tightness.

Suitable for

• Connecting metric 28 mm copper or brass pipe fittings to 5/4" male threaded components
• Plumbing systems for potable water distribution
• Heating systems and radiators with threaded supply connections
• Service and repair work where a threaded, removable joint is preferred

Key specifications

• Material: brass (bronze)
• Connection type: female internal thread (GW)
• Size: 28 mm x 5/4" (female)
• Application: potable water, heating, general plumbing
• Design: compact threaded coupling for removable joints

How to use

Before installation, ensure threads on both mating parts are clean and free of debris. Apply an appropriate thread sealant or PTFE tape to the male thread following the sealant manufacturer's instructions. Screw the SANHA female coupling onto the male thread by hand to engage threads, then tighten with a suitable wrench until secure; avoid over-tightening to prevent thread damage. For connections to 28 mm pipe fittings, use the correct fitting or adapter that matches the coupling's internal thread and pipe standard.

Usage recommendations

Verify compatibility of thread standards (metric vs imperial) and thread pitch before assembly. Use approved sealing materials for potable water applications and follow applicable plumbing codes. Inspect threaded joints periodically for signs of leakage and retighten or replace parts as necessary.
