## Long description

The kfa² flexible connector hose GW/GW 1/2" x 1/2" (model 644-030-12) is a braided plumbing connection hose with female-to-female 1/2" threaded fittings. It is designed to link taps, valves and fixtures to water supply lines where flexibility and compact routing are required. The hose absorbs minor movement and misalignment while providing a sealed water connection suitable for residential and light-commercial installations.
Advantages
This flexible connector hose offers a compact design that simplifies installation in confined spaces and behind cabinets. Its braided exterior improves resistance to abrasion and everyday wear, while the flexible interior ensures easy bending without kinking. Female-to-female 1/2" threaded fittings enable direct connection to standard plumbing fixtures and supply valves, reducing the need for additional adapters. The hose provides a reliable sealed connection for potable water systems when installed according to local plumbing standards.
Suitable for
Connecting kitchen and bathroom taps to supply valves
Linking shut-off valves and fixtures in tight or recessed spaces
Replacing worn or rigid supply lines in residential plumbing
Light-commercial installations where standard 1/2" fittings are used
Key specifications
Connector type: female-to-female (GW/GW)
Thread size: 1/2" x 1/2"
Construction: braided flexible hose with flexible inner tube
Application: potable water supply connections for taps and fixtures
Typical installation environment: indoor residential and light-commercial plumbing
How to use
Before installation, shut off the water supply and drain the line to prevent leaks. Inspect the hose ends and the mating threads on the fixture and valve for cleanliness and damage. Hand-tighten the female fittings onto the male threads, then finish with a wrench for a snug fit, avoiding over-tightening to prevent thread or seal damage. After installation, open the supply and check for leaks at both connections; if necessary, tighten slightly until the leak stops. Follow local plumbing codes and use sealing tape or washers only when required by the connection type.
Usage recommendations
Use the hose within normal household water pressure ranges and avoid exposing it to continuous high temperatures or corrosive fluids. Periodically inspect connections for signs of wear or leakage and replace the hose if any deterioration is observed. For installations involving concealed or difficult-to-access locations, ensure fittings remain serviceable and accessible for future maintenance.
