Brass Reducer Nipple Perfexim GZ 2 x 5/4 inch

Perfexim brass reducer nipple GZ 2 x 5/4 inch is a threaded pipe fitting designed to join two threaded components with different nominal diameters. Manufactured from brass, the fitting provides mechanical strength and resistance to corrosion in water, heating and low-pressure fluid systems. The part includes external (male) GZ threads in 2 inch and 5/4 inch sizes to enable a secure, tapered or parallel threaded connection depending on mating parts.

Advantages

The brass construction combines durability with good machinability and moderate resistance to dezincification in typical plumbing environments. Threaded male ends permit a straightforward, tool-assisted installation without soldering or welding. Compact reducer geometry minimises flow disruption while providing a reliable mechanical transition between different pipe sizes. The fitting is suitable for repeated assembly and disassembly when maintenance or system reconfiguration is required.

Suitable for

• Domestic and commercial plumbing connections
• Heating systems and radiators
• Low-pressure water distribution and service lines
• Temporary or permanent threaded reductions in fluid installations

Key specifications

• Material: brass
• Connection type: external (male) threaded ends
• Thread standard: G (BSP) male threads
• Sizes: 2 inch to 5/4 inch reducer
• Application pressure: suitable for low- to moderate-pressure fluid systems (plumbing/heating)
• Finish: machined brass surface

How to use

Ensure both mating threads are clean and free of debris or damaged threads prior to assembly. Apply an appropriate thread sealant such as PTFE tape or thread compound compatible with potable water if required by the installation. Thread the reducer nipple by hand to engage threads, then tighten with a suitable wrench until a firm, leak-free connection is achieved; avoid over-tightening which may damage threads. For heating systems, follow system-specific filling and pressure testing procedures after installation.

Usage recommendations

For potable water applications use approved sealing materials and verify compatibility of brass with the system medium. Inspect threaded connections during routine maintenance and replace fittings showing signs of corrosion, cracking or thread wear. Follow local plumbing codes and manufacturer guidance for maximum operating pressures and temperatures.
