Brass Extension Fitting VIEGA 3/4" 40 mm

VIEGA brass extension fitting with 3/4" thread and 40 mm length is a precision-machined brass component designed to extend the length of pipe connections in plumbing and heating installations. The fitting is intended for use where a short, threaded extension is required to achieve correct alignment or compensate for recessed fittings. Constructed from corrosion-resistant brass, it is suitable for potable water, heating and sanitary systems and provides reliable joint integrity in metal-threaded connections.

Advantages

The brass extension fitting offers dimensional accuracy and a consistent 3/4" threaded connection that ensures tight assembly with compatible fittings. Its 40 mm length provides a compact extension while maintaining mechanical stability. Machined brass construction resists corrosion in typical water and heating environments and supports long-term service life when installed according to standards. The component is compatible with common metal-threaded plumbing parts and simplifies adjustments during installation.

Suitable for

• Extending threaded pipe connections in potable water systems
• Compensating for recessed or misaligned fittings in heating installations
• Short threaded extensions in sanitary and bathroom plumbing

Key specifications

• Thread size: 3/4" (external threaded connection)
• Length: 40 mm
• Material: machined brass
• Application: potable water, heating and sanitary systems
• Corrosion resistance: suitable for typical water and heating environments

How to use

Ensure mating threads are clean and undamaged before installation. Apply an appropriate thread sealant or tape compatible with potable water if required by local practice and system specifications. Screw the extension fitting into the mating threaded connection by hand initially, then tighten with suitable tools to the torque recommended for the assembly materials and thread size. Avoid over-tightening to prevent thread damage. Verify alignment and leak-tightness after system pressurization and commissioning.

Usage recommendations

Use with fittings and pipes of the same thread specification and compatible materials. Follow local plumbing codes and manufacturer guidance for thread sealing methods and torque limits. Inspect threads for wear or damage before re-use and replace the fitting if defects are found.
