Brass Extension Nipple kfa² 1/2" (10 mm) model 170-200-98

Brass Extension Nipple kfa² 1/2" (10 mm) model 170-200-98 is a threaded plumbing fitting designed to extend or join 1/2" pipe runs. Manufactured from brass, the fitting provides corrosion resistance and mechanical durability for installations in domestic and light commercial systems. It is compatible with standard 1/2" threaded fittings and intended for use where a short, reliable extension or connection is needed in water supply lines, radiator connections, and valve adaptations.

Advantages

The brass construction offers good resistance to corrosion and scaling while maintaining dimensional stability under typical water system temperatures. Threaded ends ensure a straightforward mechanical connection with other 1/2" fittings, reducing installation time and the need for specialized tools. Its compact length makes it suitable for tight spaces where a short extension is required without altering flow characteristics significantly.

Suitable for

• Extending 1/2" water supply pipes in residential plumbing
• Connecting radiators, valves, and fixtures with 1/2" threads
• Short adaptations in heating circuits and small commercial installations
• Repairing or replacing short threaded sections in existing pipework

Key specifications

• Material: brass
• Thread size: 1/2" (compatible with standard 1/2" threaded fittings)
• Nominal thickness/diameter: 10 mm
• Finish: machined brass surface
• Application: potable water and heating systems (domestic and light commercial)

How to use

Ensure both mating threads are clean and undamaged before assembly. Apply an appropriate thread sealant or tape suitable for potable water systems if required by local practice. Hand-start the threaded connection to avoid cross-threading, then tighten with appropriate wrenches until a secure, leak-free joint is achieved without over-torquing. Recheck connections after system pressurization and during initial operation for any signs of leakage.

Usage recommendations

Use thread sealant or PTFE tape rated for drinking water where a watertight connection is required. Avoid excessive torque that can deform threads or fittings. For installations in aggressive water conditions or where dissimilar metals are present, consider appropriate dielectric fittings or corrosion protection to extend service life.
