Invena flexible connection hose GW/GW 1/2" x 3/8" (WS-02-030) for plumbing fittings

The Invena flexible connection hose GW/GW 1/2" x 3/8" (WS-02-030) is a braided supply line designed for connecting taps, valves and sanitary fittings to water supply pipes. It features a female-to-female threaded arrangement that facilitates secure installation where a compact, bendable link is required. The hose is intended for domestic and light commercial plumbing, offering corrosion-resistant properties and flexibility to route through confined spaces.

Advantages

The hose combines a flexible inner tube with an external braided cover to provide mechanical protection and resistance to kinking while maintaining flow capacity. Its threaded GW/GW connections enable straightforward attachment to standard plumbing fittings and valves without additional adapters when matching thread sizes are used. The compact construction reduces installation time in tight cabinets or under sinks and helps accommodate minor misalignments between fixed pipes and fixtures.

Suitable for

• Connecting bathroom and kitchen taps to supply lines
• Linking shut-off valves to fixtures in confined spaces
• Replacement of worn or damaged flexible supply lines
• Light commercial plumbing where domestic-grade flexible hoses are acceptable

Key specifications

• Connection type: female-to-female threaded fittings
• Thread sizes: 1/2" x 3/8"
• Construction: flexible inner tube with braided external cover
• Intended medium: potable water
• Common applications: taps, valves and sanitary fittings

How to use

Ensure water supply is shut off before disconnecting existing lines. Verify that the thread sizes on the hose match the fittings on both the fixture and the supply valve. Hand-start threads to avoid cross-threading, then tighten securely with an appropriate wrench until a leak-free connection is achieved; avoid excessive torque that could damage threads. After installation, slowly restore water pressure and inspect all joints for leaks. If necessary, tighten fittings slightly to stop minor drips.

Usage recommendations

Use this flexible hose for indoor potable water connections only, and avoid exposure to prolonged UV or outdoor conditions. Periodically inspect the hose and fittings for signs of wear, corrosion or leakage, and replace the hose if damage is detected. If installation requires lengths or connections not matching the hose, select a hose with appropriate dimensions rather than forcing incompatible fittings.
