Brass coupling SANHA 4270G GW 22 mm x 3/4"

Brass coupling SANHA 4270G GW 22 mm x 3/4" is a threaded plumbing fitting designed to connect a 22 mm outer-diameter tube to a 3/4" female thread. Manufactured from brass, this coupling provides a mechanical and sealed connection suitable for potable water and heating systems. The component is compatible with common pipe materials such as copper, steel and certain polymer pipes when the appropriate preparation and adapters are used.

Advantages

The brass construction delivers corrosion resistance and dimensional stability under typical plumbing and heating conditions. The standardized 22 mm tube interface and 3/4" female thread allow straightforward integration with existing threaded components and pipe runs. The coupling provides reliable mechanical retention and, when installed with appropriate sealing measures such as PTFE tape or joint compound, ensures serviceable leak-tight connections for water supply and heating circuits.

Suitable for

• Connecting 22 mm outer-diameter copper, steel or compatible polymer pipes to a 3/4" threaded port
• Soldered, brazed or mechanically fixed pipe runs in domestic and commercial water supply systems
• Heating system connections where a threaded transition to valves, radiators or pumps is required
• Repair or retrofit tasks involving conversion between metric tube and imperial thread fittings

Key specifications

• Material: brass
• Tube connection: for 22 mm outer-diameter pipe
• Thread type: female 3/4"
• Typical application: potable water and heating installations
• Connection method: threaded coupling (requires sealing tape or compound for leak-tight joint)

How to use

Prepare the 22 mm pipe end according to the pipe material—cut square, deburr and clean. If using copper or steel, ensure the tube is properly fitted or soldered where required by the system design. Threaded joints should be sealed with PTFE tape or an appropriate pipe joint compound applied to the male thread before engaging the coupling. Hand-start the thread to avoid cross-threading, then tighten with suitable wrenches until a secure, leak-free joint is achieved, taking care not to over-tighten brass components.

Usage recommendations

Verify compatibility of the coupling with system media and operating temperatures. Use approved sealing materials and follow local plumbing codes. For systems under pressure, perform a pressure test after installation and inspect periodically for signs of corrosion or leakage.
