Brass reducing adapter Perfexim G male 3/4" to F 1/2" (07-209-1520-000)

Perfexim brass reducing adapter with G male 3/4" to 1/2" female thread is a compact connector designed to join plumbing components with different BSP thread sizes. Manufactured from brass, the adapter provides a corrosion-resistant transition between a 3/4" male G (BSP) connection and a 1/2" female threaded fitting. It is intended for use in potable water systems and general household plumbing where compatible G (BSP) threads are present.

Advantages

The brass construction offers durability and good resistance to corrosion and wear in typical residential water systems. The reducing adapter provides a reliable mechanical connection that preserves thread sealing properties when used with appropriate tape or sealing compounds. Its compact form factor simplifies installation in confined spaces and minimizes flow disruption when reducing from 3/4" to 1/2".

Suitable for

• Connecting a 3/4" male G (BSP) pipe or fitting to a 1/2" female threaded component
• Domestic cold and hot water distribution systems with compatible threads
• Repair and modification of existing plumbing where a reduction in thread size is required
• Installation where a compact, durable threaded transition is needed

Key specifications

• Material: brass
• Thread type: G (BSP) male to female
• Input thread size: 3/4" (male)
• Output thread size: 1/2" (female)
• Application: water systems and household plumbing

How to use

Ensure both mating threads are clean and undamaged before assembly. Apply an appropriate thread sealant such as PTFE tape or approved pipe-joint compound to the male threads, wrapping in the direction of engagement. Hand-start the adapter onto the mating thread to avoid cross-threading, then tighten with a suitable wrench until secure; avoid excessive torque that could deform threads or the adapter body. After installation, pressurize the system and inspect the connection for leaks, retightening if necessary within manufacturer-recommended limits.

Usage recommendations

Use the adapter only with compatible G (BSP) threaded fittings and in systems where brass is acceptable for the conveyed medium. For potable water installations follow local plumbing codes and use approved sealing materials. Avoid exposure to aggressive chemicals or environments that accelerate dezincification; consider a dezincification-resistant alloy if required by application.
