SANHA brass nipple 4243G GZ 22 mm × 3/4" (male thread)

SANHA brass nipple 4243G GZ 22 mm × 3/4" is a threaded transition fitting made of bronze for corrosion resistance and mechanical durability. It connects a 22 mm tube end to a 3/4" female threaded component, providing a compact and robust junction between metric piping and imperial threaded fittings. The part is intended for use in plumbing and heating systems where a reliable, pressure-tight connection between different thread and tube standards is required.

Advantages

The bronze construction offers enhanced resistance to corrosion compared with standard brass alloys and ensures long-term mechanical stability in water and heating applications. The GZ (male) thread enables straightforward screwing into female threaded components, while the smooth tube end provides a secure joint with soldering, compression, or press-fit methods compatible with 22 mm tubing. The fitting’s compact length reduces dead space and simplifies installation in confined areas.

Suitable for

• Connecting 22 mm copper or compatible tubing to 3/4" female threaded valves and appliances
• Domestic and commercial plumbing systems
• Heating systems including radiators and boiler connections
• Retrofit and repair work where metric-to-imperial transitions are needed

Key specifications

• Material: bronze (SANHA brass/bronze alloy)
• Thread type: male GZ (imperial-compatible male thread)
• Tube end diameter: 22 mm
• Thread size: 3/4" (female mating)
• Application: potable water and heating systems
• Connection methods: soldering, compression fittings, or compatible press-fit systems for 22 mm tubing

How to use

Prepare the 22 mm tube by cutting squarely and deburring the inner and outer edges. Clean mating surfaces of the tube and the female threaded component to remove dirt and oxidation. For soldered joints, apply appropriate flux and solder following standard procedures for bronze/brass fittings. For compression or press-fit installations, follow the respective manufacturer’s instructions for the chosen coupling or olive. Thread the male GZ end into the female component using suitable sealing method for the application, such as PTFE tape or thread sealant rated for potable water and heating systems. Torque carefully to avoid overstressing threads or deforming the tube end.

Usage recommendations

Verify compatibility of materials and sealing methods with system media and local regulations. Use appropriate sealing products for potable water systems and adhere to recommended torque values when tightening threaded connections. Inspect joints for leaks after initial pressurization and during commissioning of plumbing or heating installations.
