## Summary description

Flexible water hose TUCAI GW DN19 EXTRA TWIST HG-3/4-300 is a DN19 diameter connection hose with a 3/4" threaded fitting and 300 mm length. Designed for potable water installations and appliance connections, it features a twist-resistant design for easier routing and secure fittings for plumbing, bathroom, and kitchen use.

## Long description

The TUCAI GW DN19 EXTRA TWIST HG-3/4-300 flexible water hose is a 300 mm connection hose with DN19 inner diameter and a 3/4" threaded fitting designed for potable water installations and appliance connections. The hose combines a compact length with a twist-resistant construction that simplifies routing in tight spaces and helps maintain secure connections under normal household water pressures. It is intended for use where a short, robust flexible connector is required between plumbing fixtures or appliances and fixed supply lines.
Advantages
The EXTRA TWIST design reduces twisting when bending the hose, making installation faster and reducing stress on fittings. The DN19 diameter and 3/4" connection provide broad compatibility with standard valves and appliances. Its 300 mm length is compact for under-sink, behind-toilet, and appliance hookup applications while offering sufficient reach for most common layouts. Materials and fittings are suitable for potable water use and designed to resist kinking during normal operation.
Suitable for
Connecting sinks, faucets and bathroom fixtures to supply lines
Hooking up dishwashers and washing machines with compatible 3/4" inlets
Short connections in tight or confined installation spaces
Temporary or permanent plumbing repairs and replacement of rigid connectors
Key specifications
Inner diameter: DN19
Connection: 3/4" threaded fitting
Length: 300 mm
Design feature: twist-resistant construction
Intended medium: potable (drinking) water
How to use
Ensure that both the supply valve and appliance are compatible with a DN19 / 3/4" connector. Before installation, shut off the water supply and relieve pressure by opening a downstream faucet. Hand-start the threaded fittings to avoid cross-threading, then tighten securely with an appropriate wrench until snug; avoid excessive torque to prevent damage to fittings. After installation, slowly open the supply valve and inspect all connections for leaks. Re-tighten if necessary and confirm proper water flow and absence of drips.
Usage recommendations
Use the hose within normal household water pressure ranges and avoid sharp bends with radii smaller than those recommended for flexible connectors. Replace the hose if you observe corrosion, visible damage, persistent leaks, or loss of flexibility. For installations with higher pressures or special requirements, consult local plumbing codes or a qualified installer to ensure appropriate selection and safe operation.
