VIEGA brass extension 3/4" (20 mm) – pipe fitting accessory

VIEGA brass extension 3/4" (20 mm) – pipe fitting accessory is a threaded brass extension designed for use in plumbing and heating systems where a 3/4" (20 mm) connection is required. The fitting provides a corrosion-resistant brass body intended to connect, extend or adapt pipe sections and components in potable water and heating installations. The compact design allows integration into existing pipe runs with standard threaded connections for straightforward assembly.

Advantages

This brass extension offers durable metal construction that resists corrosion and wear in water and heating environments. Its threaded ends enable a secure mechanical connection without reliance on flexible adapters, providing stable alignment of piping. The component is compatible with standard 3/4" (20 mm) threaded pipe fittings, simplifying replacement or modification of pipe runs. Installation and maintenance are made easier by the familiar threaded interface and the compact form factor.

Suitable for

• Extension of 3/4" (20 mm) threaded pipe runs
• Connecting or adapting components in potable water systems
• Use in heating circuits and radiator connections
• Repair or replacement of existing brass threaded fittings

Key specifications

• Material: brass (corrosion-resistant metal)
• Nominal size: 3/4" (20 mm)
• Connection type: threaded extension/fitting
• Application: potable water and heating systems
• Design: compact inline extension for standard pipe alignment

How to use

Prepare the threaded connection points by cleaning threads and applying appropriate sealing material (such as PTFE tape or approved thread sealant) according to local standards. Hand-start the brass extension onto the mating thread, then tighten with an appropriate wrench to secure a leak-free joint while avoiding over-tightening that could damage threads. Verify alignment of connected pipes and components, then test the system under working pressure and check for leaks. For heating systems, complete any required bleeding and commissioning procedures after installation.

Usage recommendations

Use in potable water and heating installations only with compatible threaded fittings and approved sealing materials. Ensure that working pressures and temperatures of the system fall within the limits appropriate for brass fittings and comply with local plumbing codes. When in doubt, consult installation guidelines or a qualified installer to confirm correct sizing and installation practices.
