Flexible plumbing hose TUCAI TAQ I3/8–V3, model 6651, flexible water connector

Flexible plumbing hose TUCAI TAQ I3/8–V3, model 6651, is a flexible water connector designed for sanitary installations. The hose features I3/8 to V3 end fittings that allow connection between common mixer outlets and valve threads. Its flexible construction simplifies installation in tight spaces and helps compensate for minor misalignment and vibration, making it suitable for residential and light commercial bathroom and kitchen plumbing.

Advantages

The TUCAI TAQ flexible hose offers a compact, bendable design that reduces installation time and enables reliable connections where rigid piping would be difficult to fit. Constructed for typical potable water use, it minimizes the risk of leaks at joints thanks to form-fit end fittings and consistent internal flow path. Flexibility helps absorb vibrations from fixtures and reduces stress on threaded connections.

Suitable for

• Connecting faucets and mixers to supply valves in bathrooms and kitchens
• Linking small plumbing appliances such as instant water heaters and filtration units
• Installations requiring flexible connections in confined or awkward spaces

Key specifications

• Connection types: one end I3/8, opposite end V3
• Application: potable water supply for sanitary fixtures
• Design: flexible hose for vibration and misalignment compensation
• Typical use environment: residential and light commercial bathrooms and kitchens

How to use

Before installation, isolate the water supply and relieve pressure. Inspect the hose and fittings for visible damage. Hand-start the threaded connections to avoid cross-threading, then tighten to the recommended torque using appropriate tools or spanners; avoid over-tightening which can damage seals. After connection, restore water supply and check for leaks at both ends. If any leakage is detected, isolate the supply and re-seat or replace seals as needed.

Usage recommendations

Use the hose only within normal cold and hot water pressures and temperatures suitable for household sanitary systems. Avoid sharp bends beyond the hose's natural curvature and prevent contact with corrosive chemicals or heat sources. Replace the flexible connector if signs of wear, kinks, or persistent leaking appear.
