Brass nipple SANHA 4243G GZ 28 mm x 3/4" (male thread)

SANHA brass nipple 4243G with GZ (male) thread, size 28 mm × 3/4", is a compact threaded adapter designed for plumbing and heating installations. Made from brass, this nipple provides corrosion resistance and reliable mechanical strength for pipe and fitting connections in water and heating systems. It joins a 28 mm connection to a 3/4" threaded port where a male threaded adapter is required.

Advantages

The brass construction ensures good resistance to corrosion and long service life in typical domestic and commercial water and heating environments. The precise machining of the threads provides a tight fit and leak-minimizing contact when installed with appropriate sealing materials. Its compact form factor allows installation in confined spaces and facilitates straightforward replacement or retrofit of existing components.

Suitable for

• Connecting 28 mm copper or brass piping to fittings or valves with 3/4" female threads
• Domestic and commercial hot and cold water distribution systems
• Heating system connections where a male-threaded adapter is required
• Retrofit and repair tasks in plumbing installations

Key specifications

• Material: brass
• Thread type: GZ (male thread)
• Connection sizes: 28 mm × 3/4"
• Application medium: potable water, heating fluids
• Typical installation environment: indoor plumbing and heating systems

How to use

Ensure that mating female threads and pipe ends are clean and free of debris. Apply an appropriate thread sealant or tape to the male threads according to local plumbing practices. Hand-start the nipple into the female thread to avoid cross-threading, then tighten with a suitable wrench until secure. Do not overtighten; follow torque recommendations for brass fittings where available. After installation, pressurize the system and inspect the joint for leaks, retightening if necessary within safe limits.

Usage recommendations

Use compatible sealing materials suitable for potable water and heating systems and avoid excessive mechanical stress on the connection. Inspect threaded joints periodically for signs of corrosion or loosening, and replace the nipple if damage or persistent leakage occurs.
