## Long description

Flexible connection hose kfa² GW/GW 1/2" x 1/2" (model 644-080-12) is a braided plumbing hose designed to connect fixtures, valves or pipes with 1/2" fittings. The hose provides a flexible water supply link that simplifies installation in confined spaces and accommodates small misalignments between connection points. Constructed for standard domestic and commercial water distribution systems, it is suitable for use where a short, flexible connection is required.
Advantages
The braided design and flexible core ensure reliable water flow while allowing bending and slight movement without stress on fittings. Threaded GW/GW 1/2" x 1/2" connections provide compatibility with common 1/2" threaded components. The compact length and flexibility make installation faster and reduce the need for precise alignment or additional adapters. Materials used resist typical household water conditions and support secure threaded joints.
Suitable for
 Connecting faucets, mixers and small valves to supply lines
 Linking appliances and fixtures in tight or awkward spaces
 Replacing rigid pipe sections to reduce stress from movement or vibration
 Temporary or permanent connections in residential and light commercial plumbing
Key specifications
 Connection type: female threaded to female threaded (GW/GW)
 Thread size: 1/2" x 1/2"
 Application: potable water supply lines and general plumbing connections
 Construction: flexible inner hose with external braided covering for strength and abrasion resistance
 Suitable environment: indoor plumbing, under-sink and fixture connections
How to use
Before installation, ensure the water supply is turned off and lines are depressurized. Inspect the hose and threaded fittings for damage or debris. Hand-start the 1/2" threaded connections and tighten using an appropriate wrench until a secure, leak-free joint is achieved; avoid excessive torque to prevent damage to fittings. After installation, open the water supply and check for leaks at both ends, tightening slightly if necessary. Periodically inspect the hose for wear, abrasion or signs of leakage.
Usage recommendations
Use the flexible connection hose for standard indoor potable water installations only. Avoid exposure to direct sunlight, high external temperatures beyond typical indoor conditions, and aggressive chemicals. Replace the hose if signs of wear, corrosion, or persistent leaks appear. For installations requiring special materials or certifications, verify compatibility with local plumbing codes and water quality conditions before use.
