Brass male adapter SANHA 4243G GZ 18 mm x 1/2" – threaded plumbing fitting

SANHA 4243G brass male adapter GZ 18 mm x 1/2" is a threaded plumbing fitting that provides a reliable transition between 18 mm copper or metal piping and 1/2" threaded fittings. Manufactured from bronze/brass alloy, the adapter is intended for use in potable water and central heating systems where a durable metal threaded connection is required. The compact design enables straightforward installation in confined spaces and is compatible with common plumbing components that accept GZ (male) threads.

Advantages

The brass construction offers corrosion resistance and long service life in domestic and light-commercial plumbing environments. The GZ male thread provides a secure mechanical joint with standard 1/2" female fittings, while the 18 mm side fits typical copper or metal pipe connections used in heating and water supply circuits. The simple geometry and proven material make the adapter suitable for repeated assembly and disassembly without significant deformation.

Suitable for

• Connecting 18 mm metal or copper pipes to 1/2" threaded valves and fixtures
• Potable water distribution systems
• Central heating installations and radiators
• Repair and modification of existing plumbing networks

Key specifications

• Material: brass/bronze alloy suitable for water and heating media
• Thread type: GZ (male) on 1/2" side
• Piping connection: 18 mm fitting side for copper/metal pipe
• Application temperature: suitable for typical domestic hot water and heating temperatures
• Connection format: threaded transition between metric pipe and imperial thread

How to use

Prepare the 18 mm pipe end by deburring and cleaning to ensure a smooth fit. Apply an appropriate thread sealant or tape to the 1/2" male thread according to local plumbing standards. Thread the adapter into the receiving 1/2" female fitting by hand, then tighten with suitable tools until secure; avoid over-tightening to prevent thread damage. Join the 18 mm side following the installation method compatible with the pipe system (push-fit, compression, or soldering) as required by the specific plumbing design.

Usage recommendations

Use compatible thread sealants approved for potable water when installing in drinking water systems. Verify system pressure and temperature limits before installation and follow local plumbing codes. For installations involving heating systems, ensure the adapter material is suitable for the operating fluid and environment. When in doubt, consult a qualified plumber to confirm correct fitting selection and installation technique.
