Flexible connection hose INVENA WS-02-040 with 1/2" female (GW) to 3/8" female connection.

## Long description

The INVENA flexible connection hose 1/2" female to 3/8" female (model WS-02-040) is a plumbing supply line designed to join fixtures with differing thread sizes. It provides a flexible link between a 1/2" female (GW) outlet and a 3/8" female inlet, allowing straightforward connection of mixers, faucets and valves where a reduction of thread size is required. The hose construction accommodates slight misalignment and eases installation in confined spaces without the need for rigid pipe adjustments.
Advantages
The hose offers flexibility and compact dimensions that simplify connections in tight installations. Its female-to-female configuration eliminates the need for additional adapters when connecting a 1/2" supply to a 3/8" fitting. The design allows small angular adjustment and reduces stress on fittings, helping to maintain water-tight joints. The product is intended for standard domestic and light commercial plumbing applications and is compatible with common mixer and tap fittings that use these thread sizes.
Suitable for
Connecting a 1/2" female water supply outlet to a 3/8" female mixer or faucet inlet
Retrofit and repair work where thread reduction is necessary
Installations in confined or hard-to-reach spaces that require a flexible connection
Domestic kitchens, bathrooms and utility room plumbing
Key specifications
Connection sizes: 1/2" female to 3/8" female
Type: flexible connection hose for plumbing fixtures
Use: indoor water supply lines for mixers, faucets and valves
Compatibility: standard 1/2" and 3/8" threaded fittings commonly used in residential plumbing
Function: allows slight alignment adjustment and absorbs minor movement
How to use
Before installation, shut off the water supply and relieve pressure by opening the local tap. Inspect the hose ends and mating fittings to ensure threads and sealing surfaces are clean and undamaged. Hand-start the connections to the 1/2" and 3/8" female threads, then tighten by hand and finish with an appropriate spanner if required, taking care not to overtighten. After installation, turn the water supply back on and check all joints for leaks. If any leakage is detected, tighten slightly or reseat the connection.
Usage recommendations
Use appropriate sealing materials only where recommended by the fixture manufacturer; avoid excessive force during tightening to prevent damage to threads. Periodically inspect the hose and connections for signs of wear, corrosion or leakage and replace if necessary to maintain a reliable water seal.
