## Long description

Flexible connection hose kfa 1/2" (female) to 3/8" (female) model 645-050-38 is a compact plumbing hose designed to connect fixtures with different thread sizes. The hose provides a flexible link between a water supply line and sanitary fittings such as taps and mixers, accommodating tight installation spaces and minor misalignments while maintaining water-tight performance.
Advantages
The hose offers flexibility that simplifies installation in confined areas and reduces stress on fixed piping. Constructed for standard domestic water supply use, it enables quick replacements and retrofits without major changes to existing plumbing. Its dual female thread configuration allows direct connection between a 1/2" inlet and a 3/8" fitting, helping to bridge common thread mismatches in household installations.
Suitable for
 Connecting kitchen and bathroom taps to supply lines
 Linking mixers and single-lever faucets to water inlets
 Replacing worn or damaged flexible hoses in sanitary installations
 Plumbing work in tight or confined spaces where rigid pipes are impractical
Key specifications
 Connection types: female 1/2" to female 3/8"
 Application: cold and hot domestic water supply
 Form factor: flexible hose for sanitary fittings
 Typical installation environment: indoor plumbing for taps and mixers
 Compatibility: designed for fixtures and supply lines that accept 1/2" and 3/8" female threads
How to use
Ensure both connection points are clean and match the indicated thread types. Hand-start the hoses on each fitting to avoid cross-threading, then tighten with an appropriate wrench until secure; avoid overtightening to prevent damage to threads or sealing elements. After installation, open the water supply slowly and check for leaks at both connections. If leaks occur, tighten slightly or reseat sealing washers where applicable. Regularly inspect the hose for signs of wear, kinks, or corrosion and replace when necessary.
Usage recommendations
Use the hose for indoor domestic water supply applications only. Verify thread compatibility before installation and replace the hose if any visible damage or persistent leakage is present. For installations involving high water pressure, extreme temperatures, or critical systems, consult a qualified plumber to ensure suitability and compliance with local regulations.
