Brass reducer fitting Perfexim GW–GZ 1 x 3/4" (female–male)

Perfexim brass reducer fitting GW–GZ 1 x 3/4" (female–male) is a threaded plumbing adapter designed to join a 1" female (GW) connection to a 3/4" male (GZ) connection. Manufactured from brass, the fitting provides corrosion resistance and mechanical durability suitable for domestic and light commercial water installations, repair and retrofit tasks. The compact, solid design ensures a reliable threaded transition between differing pipe or fixture sizes without the need for soldering or complex adapters.

Advantages

The brass construction resists corrosion and ensures long-term mechanical strength in potable water and non-aggressive fluid systems. The threaded female-to-male configuration enables a straightforward conversion between 1" and 3/4" threaded components, reducing the number of joints and potential leak points. Installation is quick and compatible with standard threaded plumbing connections, and the compact profile minimizes space requirements in tight installations.

Suitable for

• Connecting a 1" female threaded pipe or fitting to a 3/4" male threaded fixture
• Domestic water supply repairs and retrofits
• Light commercial plumbing installations
• Temporary or permanent threaded transitions in piping systems

Key specifications

• Material: brass (corrosion-resistant)
• Connection type: female 1" (GW) to male 3/4" (GZ) threaded
• Application: cold and hot water installations, non-aggressive fluids
• Design: compact, solid body for threaded connection
• Installation method: threaded joint (requires suitable sealing such as PTFE tape or thread sealant)

How to use

Ensure mating threads are clean and undamaged before assembly. Apply an appropriate thread sealant or PTFE tape to the male threads to prevent leaks, then hand-start the fitting into the 1" female thread and tighten with an appropriate wrench until snug; avoid over-tightening to prevent thread damage. Check the connection under pressure and inspect for leaks; re-tighten or reapply sealant if necessary. For installations exposed to extreme temperatures or aggressive fluids, confirm material compatibility before use.

Usage recommendations

Use compatible sealing materials (PTFE tape or liquid thread sealant) and avoid soldering or heating the brass fitting. For potable water systems follow local plumbing codes and, when in doubt, consult a qualified plumber to ensure correct installation and sealing.
