## Long description

Flexible connection hose kfa² 1/2" male to 3/8" male (model 645-030-38) is a compact plumbing accessory designed to connect fixtures with differing thread sizes. The hose provides a flexible link between a 1/2" male threaded outlet and a 3/8" male inlet, allowing installation of faucets, mixers and other sanitary fittings where pipe thread adaptors are required. It is intended for potable water systems and standard indoor plumbing replacements.
Advantages
The hose combines flexibility and compact length to simplify tight installations under sinks and behind mixers. Constructed for compatibility with common plumbing threads, it reduces the need for additional adapters and minimizes water stress at connection points. Its flexible design facilitates alignment between mismatched fittings while maintaining a continuous potable water path.
Suitable for
Connecting kitchen and bathroom faucets to supply lines with different thread sizes
Under-sink installations in confined spaces
Replacement of rigid pipe sections where flexibility is required
Plumbing repairs and retrofits in residential and light commercial environments
Key specifications
Connection ends: 1/2" male to 3/8" male
Application: potable water systems and standard indoor plumbing
Type: flexible connection hose for sanitary fittings
Typical use: faucets, mixers and under-sink supply connections
Form factor: compact, flexible hose suitable for confined spaces
How to use
Shut off the water supply before installation and relieve pressure by opening a downstream tap. Hand-start the threads on both ends to avoid cross-threading, then tighten with an appropriate tool until a secure, leak-free seal is achieved; do not overtighten. Inspect connections for leaks after turning the water back on and check both ends during initial use. Replace the hose if visible wear, kinking or persistent leakage occurs.
Usage recommendations
Use the hose only in cold and hot potable water systems within typical household pressure ranges. Avoid sharp bends or sustained kinks that could restrict flow or weaken the hose. If installation requires additional adaptors or pressure-reducing devices, select compatible fittings rated for potable water use.
