## Long description

Flexible connecting hose kfa 644-050-12 with female threaded connections 1/2" x 1/2" is a flexible water connector intended for linking plumbing fixtures, taps and valves. The hose provides a compact, bendable connection that accommodates small misalignments between fixed pipework and appliances. Constructed for domestic and light commercial installations, it offers a straightforward solution where two female 1/2" threads are required for water supply lines.
Advantages
The kfa 644-050-12 connecting hose combines flexibility with a standard female 1/2" x 1/2" threaded interface, simplifying installation in tight spaces. Its flexible body reduces stress on rigid pipework and helps prevent leaks caused by misalignment. The hose is suitable for repeated connection and disconnection and is compatible with common plumbing fittings used in household and light commercial applications.
Suitable for
 Connecting water taps to supply lines with female 1/2" threads
 Linking valves and fixtures where flexibility and small alignment tolerance are needed
 Bathroom and kitchen installations in residential buildings
 Light commercial plumbing where a compact flexible connection is required
Key specifications
 Connection type: female threaded – female threaded, 1/2" x 1/2"
 Application: cold and hot water supply (domestic and light commercial)
 Design: flexible hose for compensating misalignment and movement
 Typical length: compact fit for installations with limited space (verify specific length before installation)
 Material: flexible inner tube with protective outer cover (materials typical for potable water fittings)
How to use
Shut off the water supply before installation. Ensure mating threads on the tap and supply pipe are clean and compatible with a 1/2" female threaded connection. Hand-start the hose nuts onto the male threads to avoid cross-threading, then tighten using an appropriate wrench until secure; avoid over-tightening. After installation, open the water supply and check for leaks at both threaded joints. If any leakage is detected, tighten slightly or reseat the connection. Follow local plumbing codes and use thread sealant or washers where required by the fixture design.
Usage recommendations
Inspect the hose periodically for signs of wear, kinking or external damage and replace if any defects appear. Use the product within manufacturer temperature and pressure limits typical for potable water fittings and avoid exposure to corrosive chemicals. When replacing existing connections, verify thread compatibility and hose length to ensure a correct fit.
