Brass reducer fitting Perfexim 3/4" female thread to 1/2" male thread

Perfexim brass reducer fitting 3/4" female to 1/2" male thread is a compact plumbing adapter designed to connect components with different thread sizes. Made of brass, the fitting offers resistance to corrosion and reliable mechanical strength for typical residential and light commercial water system use. It is intended for installation between hoses, pipes, valves or fixtures where a transition from a larger female thread to a smaller male thread is required.

Advantages

The brass construction provides good corrosion resistance and long service life in contact with potable water. Machined threads ensure a tight mechanical connection and reduce the risk of leaks when installed with appropriate sealing tape or sealant. The compact form factor requires minimal space and allows direct adaptation without additional couplings, simplifying repair and installation tasks.

Suitable for

• Adapting plumbing fixtures with 3/4" female thread to 1/2" male threaded pipes or hoses
• Repairing or modifying domestic water supply lines and fittings
• Light commercial plumbing applications where thread size transition is needed

Key specifications

• Material: brass for corrosion resistance and durability
• Connection type: female-to-male threaded reducer
• Thread sizes: 3/4" female (internal) to 1/2" male (external)
• Suitable media: cold and hot potable water
• Typical applications: pipe, valve and fixture connections in plumbing systems

How to use

Before installation, inspect threads for damage and clean mating surfaces. Apply suitable thread sealant or PTFE tape to the male thread to ensure a watertight joint. Screw the reducer into the 3/4" female connection by hand to start, then tighten with an appropriate wrench until secure; avoid over-tightening to prevent thread deformation. Connect the 1/2" male thread to the corresponding female fitting, again using sealant as required, and check the assembled connection for leaks under normal pressure.

Usage recommendations

Use in potable water systems and standard domestic or light commercial plumbing. Avoid exposure to aggressive chemicals and excessive mechanical stress. For installations subject to high pressure, thermal cycling, or specific regulatory requirements, verify compatibility with system specifications and local codes before use.
