Brass threaded coupling IBP 18 x 1/2 (mufa) — IBP BRAZ MUFA GW 18X1/2

Brass threaded coupling IBP 18 x 1/2 (mufa) — IBP BRAZ MUFA GW 18X1/2 is a brass pipe connector designed to join an 18 mm outer-diameter pipe to a 1/2" BSP threaded fitting. Manufactured from brass to provide corrosion resistance and reliable mechanical strength, this coupling is suitable for plumbing, heating and water installations in residential and commercial settings. The component enables repair, extension or reconfiguration of pipe runs where a transition between metric tubing and standard BSP threads is required.

Advantages

The brass construction offers good resistance to corrosion and wear while maintaining dimensional stability under typical plumbing temperatures and pressures. The threaded design provides a secure mechanical connection without the need for soldering or welding, simplifying installation and future disassembly. Compact dimensions and standard thread form ensure compatibility with common 1/2" BSP fittings and 18 mm piping used in heating and water systems.

Suitable for

• Joining 18 mm outer-diameter copper, brass or compatible tubing to 1/2" BSP threaded fixtures
• Repairs and extensions of potable water supply lines
• Connections in central heating circuits and radiators
• Plumbing installations in residential and commercial buildings

Key specifications

• Material: brass
• Connection A: 18 mm outer diameter pipe coupling
• Connection B: 1/2" BSP (female/mufa) threaded interface
• Suitable medium: water and heating fluids compatible with brass
• Typical application temperature range: standard plumbing and heating system temperatures

How to use

Prepare mating pipe ends by cutting square and removing burrs. Ensure the 18 mm pipe is clean and properly inserted to the required depth. Apply appropriate thread sealant or tape to the 1/2" BSP male thread if required by the installation practice. Hand-start the threads to avoid cross-threading, then tighten with a suitable wrench until secure; avoid excessive torque to prevent deformation of the coupling or connected fittings. After assembly, pressure-test the system according to applicable standards and check for leaks.

Usage recommendations

Use compatible pipe materials and follow local plumbing codes. For potable water systems, ensure any sealing material is approved for drinking water. If the installation involves aggressive fluids, consult compatibility data for brass. Periodically inspect threaded connections for signs of corrosion or leakage and re-tighten or replace components as needed.
