kfa² brass extension 1/2" (25 mm) model 170-203-98

kfa² brass extension 1/2" (25 mm) model 170-203-98 is a short, rigid brass spacer intended to increase the effective length of a pipe or fitting in water and heating installations. The extension features a 1/2" (25 mm) connection and a solid brass body that delivers mechanical stability and resistance to corrosion in domestic and professional plumbing systems. It is suitable for situations where a fixed metallic spacer is preferred over flexible connectors or where small adjustments to pipe alignment and overall length are required.

Advantages

The brass construction offers good corrosion resistance and long-term dimensional stability under typical potable water and heating conditions. Its compact 25 mm length makes it useful for tight installation spaces while maintaining a rigid connection. The product is compatible with standard 1/2" fittings and provides a simple mechanical solution to extend or align pipes without introducing additional flexible joints.

Suitable for

• Extending 1/2" water supply or heating pipes by 25 mm
• Compensating small gaps when aligning fittings or valves
• Use as a rigid spacer in bathroom, kitchen and boiler-room installations
• Professional plumbing work where metallic connections are required

Key specifications

• Material: solid brass
• Connection size: 1/2" (25 mm)
• Effective extension length: 25 mm
• Application: potable water and heating systems
• Form: rigid straight extension spacer

How to use

Shut off the water supply and drain the section of the system before installation. Prepare mating threads or connection points by cleaning and, where required, applying appropriate sealing such as thread tape or joint compound compatible with potable water. Thread the brass extension into the mating fitting or valve by hand, then tighten with an appropriate wrench to the torque recommended for the connected fittings, avoiding excessive force that could damage threads. After installation, restore supply and check for leaks at the connection points.

Usage recommendations

Use this brass extension in installations compatible with metallic spacers and where a fixed, non-flexible connection is acceptable. Verify material compatibility with system fluids and temperature ranges; avoid use with aggressive chemicals or environments that can cause dezincification unless the material specification for the specific batch confirms resistance. Periodically inspect connections for leaks and maintain according to normal plumbing practice.
