## Long description

Brass Threaded Extension INVENA H/ZM-11-230 1/2" external/internal x 30 mm is a solid brass connector designed to extend or adapt threaded plumbing fittings. With a 30 mm body and matched 1/2" external and internal threads, this extension enables secure screw-in connections between components where additional length or adjustment of installation depth is required. The brass material offers corrosion resistance appropriate for cold and hot water supply systems in domestic and light commercial installations.
Advantages
The extension is manufactured from solid brass for durability and reliable performance in typical water supply environments. Its matched external and internal 1/2" threads provide compatibility with standard threaded fittings, reducing the need for additional adapters. The compact 30 mm length allows precise adjustment of installation depth while maintaining a stable threaded joint. Its straightforward mechanical design ensures simple installation and long-term dimensional stability.
Suitable for
 Extending threaded connections in residential water supply systems
 Adjusting mounting depth for taps, valves and fixtures

Key specifications
 Material: brass
 Thread type: 1/2" external and 1/2" internal threads
 Length: 30 mm
 Application: water supply fittings and fixtures
 Finish: natural brass surface
How to use
Prepare mating threads by cleaning and removing debris or old sealant. Apply an appropriate thread sealant or PTFE tape to the male thread if required for a watertight joint. Screw the extension into the existing female or male fitting by hand until engaged, then tighten with a suitable wrench to the required torque, taking care not to over-tighten and deform the threads. After installation, check for leaks and re-tighten slightly if necessary following pressure testing procedures.
Usage recommendations
Use compatible thread sealants rated for potable water systems when connecting to drinking water supply lines. Avoid excessive mechanical stress or bending loads on the extension; provide support for connected pipes or fixtures to prevent joint fatigue. For installations involving dissimilar metals, consider appropriate dielectric fittings or anti-corrosion measures to prevent galvanic corrosion.
