## Long description

The TUCAI water connection hose reducer HG-3/8-1/2, 700 mm length, model 5813, is a flexible plumbing connector designed to join fixtures or appliances with differing thread sizes. This hose features a HG-3/8 to 1/2 thread configuration and a 700 mm overall length, providing a straightforward connection between components that require a reduction in thread diameter. Constructed for use in domestic and light commercial plumbing, the TUCAI reducer is intended to deliver a reliable water supply link where compatibility between fittings is otherwise limited.
Advantages
The hose reducer offers flexibility and ease of installation when adapting between HG-3/8 and 1/2 threaded connections. Its 700 mm length provides sufficient reach in typical sink, basin or appliance installations while allowing for some routing and positional adjustment. Designed for plumbing use, the component reduces the need to replace existing fixtures or use multiple adapters and supports a neat, compact connection in confined spaces.
Suitable for
Connecting faucets, mixers or taps with HG-3/8 fittings to appliances or supply lines with 1/2 thread
Bathroom and kitchen sink installations where a size reduction is required
Light commercial plumbing projects with standard domestic water pressures
Replacement or refurbishment of existing flexible supply lines to match different thread sizes
Key specifications
Thread configuration: HG-3/8 to 1/2
Overall length: 700 mm
Function: Reducing flexible water connection hose for potable water supply lines
Typical applications: Fixture-to-supply and appliance connections in domestic and light commercial settings
How to use
Shut off the water supply before installation and relieve pressure by opening a downstream tap. Verify thread directions and clean mating threads on both fixtures. Hand-start the HG-3/8 and 1/2 threaded ends to avoid cross-threading, then tighten to a firm fit using an appropriate wrench if required; avoid excessive torque to prevent damage to fittings. Once fitted, open the water supply and check all connections for leaks. If leaks occur, tighten slightly or reseal threads according to the installation context and applicable plumbing standards.
Usage recommendations
Use this TUCAI reducer hose in installations where a compact, flexible connection is needed between HG-3/8 and 1/2 threaded components. Ensure compatibility with the system's pressure and temperature requirements, and replace the hose if signs of wear, corrosion or damage appear. For long-term reliability, follow local plumbing codes and, where applicable, use approved sealing methods for threaded joints.
