## Long description

Brass extension nipple kfa² 1/2" (20 mm) model 170-202-98 is a threaded plumbing adapter designed to extend or connect 1/2-inch (20 mm) pipe fittings. Manufactured from brass, this coupling provides corrosion-resistant mechanical strength and reliable thread engagement for household and light commercial water systems, radiators, valves and general repair tasks.
Advantages
The brass construction ensures durability and resistance to corrosion in typical potable water and heating environments. Precision-cut threads provide a tight mechanical fit that minimizes the risk of leaks when paired with appropriate sealing materials. Its compact 1/2" (20 mm) size allows straightforward integration into existing installations and enables quick on-site modifications or repairs without the need for specialized tools.
Suitable for
 Extending or connecting 1/2" (20 mm) pipe fittings in domestic plumbing
 Connecting radiators, valves and shut-off fittings
 Repairing or modifying water supply lines in kitchens and bathrooms
 Light commercial plumbing applications requiring threaded brass connectors
Key specifications
 Material: Brass (corrosion-resistant)
 Threaded connection: 1/2" (20 mm) standard plumbing thread
 Shape: Straight extension nipple
 Intended use: Mechanical threaded join for water and heating systems
 Typical operating environment: Domestic and light commercial potable water and heating installations
How to use
Ensure mating threads are clean and free of debris before installation. Apply an appropriate sealing method such as PTFE tape or liquid thread sealant to the male threads to achieve a watertight connection. Screw the extension nipple into the female fitting by hand until snug, then tighten with an appropriate wrench to the manufacturer-recommended torque or until the joint is secure without over-tightening. After installation, pressurize the system and inspect the joint for leaks; if leakage occurs, depressurize, disassemble and reapply sealant or retighten as needed.
Usage recommendations
Use appropriate thread sealants compatible with potable water systems and avoid excessive torque to prevent thread damage. For installations in aggressive water conditions or where electrolytic corrosion is possible, consider isolating dissimilar metals with suitable fittings or dielectric unions. Follow local plumbing codes and safety practices when integrating into water or heating systems.
