## Long description

Flexible connection hose kfa² 3/8" x 3/8" (model 644-050-38) is a compact supply line designed to connect faucets and other water fittings. With female-to-female 3/8" threaded ends, this hose provides a flexible and space-saving link between fixed supply pipes and fixtures. It is intended for potable water installations and for short runs where a reliable, durable connection is required in domestic bathroom and kitchen plumbing.
Advantages
The hose combines a flexible braided exterior with internal water-grade materials to resist kinking and to maintain flow under normal domestic pressure. Its short length and female-to-female threaded ends simplify replacement and installation near sinks, washbasins, and other confined locations. Designed for potable water use, the construction minimizes risk of leaks when properly fitted and tightened to standard plumbing connectors.
Suitable for
 Connecting kitchen and bathroom faucets to supply valves
 Replacing short, worn flexible hoses in domestic plumbing
 Linking mixers, taps and other fittings where a 3/8" female-to-female connection is required
 Compact installations with limited space behind fixtures
Key specifications
 Connection type: female-to-female threaded ends, 3/8" x 3/8"
 Intended use: potable water supply
 Design: flexible hose with braided outer layer for durability
 Application area: short connection runs for sinks, basins, and water fittings
How to use
Shut off the water supply before starting installation. Ensure mating threads on the supply valve and fixture are clean and free of debris. Hand-start the hose onto the threaded connections, then tighten securely with an appropriate wrench until a snug, leak-free fit is achieved; avoid overtightening. After installation, open the water supply and check for leaks at both connections. If necessary, retighten slightly or reseal threads according to local plumbing practice.
Usage recommendations
Use the hose only on potable water systems and within the manufacturer’s recommended pressure and temperature ranges for flexible connectors. Inspect periodically for signs of wear, corrosion, or external damage and replace if deterioration is observed. For installations in concealed locations, allow access for future inspection or replacement and follow local plumbing codes.
