Brass extension fitting VIEGA 3/4" 30 mm

Brass extension fitting VIEGA 3/4" 30 mm is a threaded brass coupling designed to extend the effective thread length of 3/4" plumbing connections. Manufactured from solid brass, this 30 mm extension provides a corrosion-resistant interface suitable for potable water systems and general plumbing applications. It fits standard 3/4" threaded pipe fittings and adapters, enabling precise alignment and additional engagement where existing thread depth is insufficient.

Advantages

The solid brass construction delivers durable corrosion resistance and long service life in water installations. Its standardized 3/4" thread and 30 mm length make it compatible with common plumbing fittings and adapters, reducing the need for machining or custom parts. The compact, simple design ensures easy installation and reliable mechanical connection without affecting flow characteristics.

Suitable for

• Extending thread engagement on 3/4" plumbing connections
• Adapting mismatched fittings where additional thread length is required
• Residential potable water installations and commercial plumbing systems
• Repair tasks where replacing pipe sections is impractical

Key specifications

• Material: solid brass for corrosion resistance
• Connection size: nominal 3/4" threaded
• Extension length: 30 mm
• Compatibility: standard 3/4" threaded pipe fittings and adapters
• Application: potable water and general plumbing use

How to use

Ensure both mating threads are clean and undamaged before installation. Apply an appropriate thread sealant or PTFE tape to the male thread per local plumbing codes. Thread the brass extension fitting into the female port by hand to start, then tighten with a wrench to the required torque without over-tightening to avoid deforming the threads. Once installed, check for leaks under working pressure and re-tighten if necessary following recommended torque limits.

Usage recommendations

Use thread sealant compatible with potable water systems and follow local plumbing regulations. Avoid excessive force during tightening and inspect connections periodically for signs of wear or corrosion. For applications involving aggressive media, verify material compatibility before use.
