## Long description

Flexible connection hose kfa² 1/2" x 1/2" (model 644-100-12) is a compact flexible water supply hose designed for indoor sanitary installations. It features female 1/2" threaded ends to connect mixers, shut-off valves and appliances where a movable or slightly adjustable connection is required. The hose is intended to provide a reliable, space-saving link between fixed plumbing points and fixtures such as faucets, sinks and small water heaters.
Advantages
The hose offers flexibility that simplifies alignment between plumbing components without the need for precise rigid piping. Its female threaded ends make installation straightforward with common 1/2" fittings. The compact design allows use in confined spaces under sinks or behind cabinets while maintaining steady water flow. Materials and construction provide resistance to routine bending and typical household water pressures.
Suitable for
 Connecting bathroom and kitchen faucets to shut-off valves
 Linking sinks and basins to water supply points
 Connecting small water heaters or inline appliances
 Situations requiring a short, flexible connection in tight spaces
Key specifications
 Connection type: female threaded 1/2" x 1/2"
 Application: indoor potable water supply for sanitary fittings
 Design: flexible hose for short-distance connections
 Typical use locations: under sinks, behind cabinets, near mixers
 Compatibility: standard 1/2" plumbing fittings and valves
How to use
Ensure the water supply is turned off before beginning installation. Attach one female 1/2" end of the hose to the threaded outlet of the shut-off valve and the other female 1/2" end to the threaded inlet of the mixer or appliance. Hand-tighten the connections and then use an appropriate wrench to secure them with a partial turn; avoid over-tightening which can damage threads or fittings. After installation, turn the water on and check all joints for leaks, tightening slightly if necessary.
Usage recommendations
Use compatible 1/2" threaded fittings and avoid excessive bending or repeated sharp kinks. Inspect connections periodically for signs of wear or leakage and replace the hose if any damage or persistent leaks are detected. For installations exposed to freezing temperatures or abnormal mechanical stress, choose hoses and routing that minimize risk of damage.
