Brass Extension Pipe Perfexim 1/2" GW - GZ × 50 mm, model 07-220-1550-000

Perfexim brass extension 1/2" GW - GZ × 50 mm is a short threaded coupling intended to extend or connect two 1/2-inch plumbing fittings. Manufactured from brass, the extension delivers corrosion resistance and stable mechanical connection for water supply, heating circuits and general pipe assembly where a 50 mm extension is required.

Advantages

The brass construction provides good resistance to corrosion and moderate mechanical stress while preserving thread integrity for repeated installation and removal. Its compact 50 mm length allows precise alignment and small positional adjustments in tight installations. The standard 1/2" female-to-male thread interface ensures compatibility with common plumbing fittings and valves, enabling straightforward integration into existing pipework.

Suitable for

• Extending or joining 1/2" threaded water supply pipes
• Connecting valves, faucets and fittings in residential plumbing
• Minor alignment corrections in heating system piping
• General maintenance and repair work on threaded pipe assemblies

Key specifications

• Material: brass
• Thread type: female to male 1/2" (GW - GZ)
• Length: 50 mm
• Application: water plumbing and heating systems
• Finish: natural brass surface

How to use

Confirm that both mating threads are clean and free of debris or old sealant. Hand-start the fitting on the mating thread to avoid cross-threading, then tighten by wrench to a secure, leak-free fit. Use appropriate sealing method for the installation (thread seal tape or paste) following manufacturer guidance for the system media and pressure. Avoid excessive torque to prevent thread damage or deformation of the brass body.

Usage recommendations

For durable joints, apply an appropriate thread sealant and tighten to the recommended torque for 1/2" brass fittings. Inspect connections periodically for signs of leakage or corrosion, especially in hard-water or high-temperature installations. Do not use with aggressive chemicals incompatible with brass.
