Copper Alloy Nipple SANHA 4243G GZ 28 mm x 5/4" — pipe fitting, model 1424328114

SANHA 4243G is a copper alloy (bronze) nipple with a GZ male threaded connection sized 28 mm x 5/4". It is engineered as a compact pipe fitting for creating a secure threaded joint between pipes or threaded components in plumbing and heating installations. The bronze construction provides enhanced corrosion resistance compared to standard copper in aggressive water and heating environments, making the fitting suitable for long-term use where durable metal threaded connections are required.

Advantages

The bronze (copper alloy) material offers good resistance to corrosion and dezincification in potable water and heating circuits. The GZ male thread provides a standard, reliable sealing interface for compatible female threaded parts. The solid machined design ensures dimensional stability and a consistent thread profile for leak-tight assemblies when used with appropriate sealing methods. Its compact length and standardized thread dimensions simplify replacement and retrofit work in existing systems.

Suitable for

• Joining pipes and threaded fittings in residential plumbing systems
• Connections in heating circuits and radiator installations
• Sanitary installations where metal threaded joints are required
• Retrofit and repair work on existing threaded pipe networks

Key specifications

• Material: copper alloy (bronze)
• Thread type: GZ (male thread)
• Size: 28 mm x 5/4"
• Application: plumbing, heating, sanitary systems
• Design: machined nipple for threaded connections

How to use

Prepare both mating threads by cleaning and removing any debris or old sealant. Apply an appropriate thread sealant (such as PTFE tape or approved pipe joint compound) to the male thread following the sealant manufacturer's instructions. Screw the nipple into the compatible female GZ thread by hand until engagement, then tighten with a suitable wrench to the recommended torque for the pipe size and material to avoid overstressing the fitting. Verify alignment and perform a pressure test according to installation standards and local regulations.

Usage recommendations

Use thread sealants compatible with bronze and potable water when installing this copper alloy nipple. Avoid excessive tightening; follow industry torque guidelines for 28 mm / 5/4" threaded joints. For installations in aggressive water conditions or where dezincification risk exists, periodic inspection is advisable to ensure continued leak-free performance.
