Featuring F3/8" and F1/2" female threaded ends, this hose ensures a secure and leak-proof connection for plumbing fixtures.

## Long description

The TUCAI flexible hose, measuring 40 cm in length, is a high-quality braided connector engineered for dependable water supply applications. Designed with F3/8" and F1/2" female threaded connections, this hose facilitates a secure and watertight link between plumbing fixtures and water supply lines. Its robust construction ensures long-term durability, providing the necessary flexibility to navigate tight spaces while maintaining resistance to internal water pressure, making it a reliable component for both residential and commercial plumbing systems.
Advantages
This flexible hose offers exceptional reliability due to its high-grade braided exterior, which protects the inner tube from external damage and kinking. The precision-engineered threaded ends ensure a tight seal, significantly reducing the risk of leaks and water damage. Its 40 cm length provides sufficient reach for standard installations, while the flexible design simplifies the connection process in confined areas, such as under sinks or behind toilets, without compromising the integrity of the water flow.
Suitable for
Connecting kitchen and bathroom faucets to water supply valves
Installing toilet cisterns to water inlets
General residential plumbing maintenance and repairs
Commercial sanitary equipment installations
When it may not be suitable
This hose is not intended for use in high-temperature heating systems or industrial applications involving aggressive chemicals or extreme pressure levels exceeding standard residential plumbing requirements. It should not be used in environments where it may be exposed to direct sunlight or corrosive substances that could degrade the braided material over time.
Key specifications
Length: 40 cm
Connection type: Female 3/8" to Female 1/2"
Material: Braided metal exterior with flexible inner core
Application: Water supply systems
How to use
To install the hose, ensure the water supply is turned off at the isolation valve. Clean the connection points on both the fixture and the supply pipe to remove any debris or old sealant. Align the F3/8" and F1/2" ends with the respective ports and tighten the nuts by hand until firm. Use a suitable wrench to tighten the connections further, taking care not to overtighten, which could damage the internal gaskets. Once installed, slowly turn on the water supply and inspect the connections for any signs of moisture or leaks.
What to consider before purchase
Verify the thread sizes of your existing fixtures to ensure compatibility with F3/8" and F1/2" connections
Measure the required distance between the supply valve and the fixture to confirm that 40 cm is sufficient
Ensure the hose is not stretched or kinked during installation to maintain optimal performance
Usage recommendations: Regularly inspect the hose for signs of wear, corrosion, or dampness, especially in areas with high humidity. Replace the hose if any damage to the braided exterior is visible to prevent potential water leaks.
