To install the TUCAI flexible hose, ensure that the water supply is turned off and the area is clear of debris. Align the M3/8 and F3/8 threaded ends with the corresponding fixture and supply valve ports. Tighten the connections manually or with a suitable wrench, ensuring not to overtighten, which could damage the seals. Once installed, slowly turn on the water supply and inspect the connections for any signs of leakage before finalizing the setup.
What to consider before purchase
Verify the required thread size (M3/8-F3/8) for your specific fixture
Measure the distance between the supply valve and the fixture to ensure 30 cm is sufficient
Check the operating pressure and temperature of your water system
Ensure compatibility with local plumbing standards
For optimal performance and safety, it is recommended to inspect the hose periodically for signs of wear or calcification. Avoid bending the hose at sharp angles during installation to prevent kinking, which could restrict water flow or weaken the structure over time.
