Brass Extension Fitting FERRO P120Z 3/4" (20 mm) for Plumbing Connections

FERRO P120Z 3/4" (20 mm) brass extension fitting is a threaded plumbing accessory designed to extend or adapt fittings in water supply and heating installations. Manufactured from brass, this extension provides a short, robust connection between valves, taps and threaded pipe fittings, allowing precise alignment or added length where needed. The product name and basic application—extension fitting for plumbing connections—are reflected in its design to meet common residential and commercial installation needs.

Advantages

The brass construction offers corrosion resistance and mechanical strength suitable for potable water and heating systems. The 3/4" (20 mm) nominal size matches standard threaded fittings, ensuring compatibility with common valves and connectors. Its compact length simplifies installation in confined spaces and reduces the need for multiple components. Threaded ends enable secure, leak-resistant joins when installed with appropriate sealing materials.

Suitable for

• Extending threaded valves and taps in water supply systems
• Adapting fittings in domestic heating installations
• Connecting short pipe runs where extra threaded length is required
• Plumbing repairs and retrofit work in residential and light commercial projects

Key specifications

• Form factor: short, straight threaded coupler/extension

How to use

Prepare mating threads by cleaning and inspecting for damage. Apply an appropriate thread sealant or tape to the male threads following the sealant manufacturer's instructions. Thread the FERRO P120Z extension fitting hand-tight, then use suitable wrenches to make the final connection without over-torquing to avoid damaging threads. Ensure alignment with adjoining fittings and verify that the assembly is supported to prevent undue stress on the pipework. Pressurize the system and inspect for leaks, retightening if necessary within recommended torque limits.

Usage recommendations

Use suitable thread sealants compatible with potable water if the fitting is installed on drinking water lines. Avoid excessive torque during installation and ensure the fitting is used within the temperature and pressure limits of the overall system. For exposed or outdoor installations consider additional protection against galvanic corrosion when connecting to dissimilar metals.
