How to use
To install the hose, ensure the water supply is turned off at the isolation valve. Clean the connection points to remove any debris or old sealant. Attach the M3/8" end to the supply valve and the F3/8" end to the fixture, ensuring that the rubber gaskets are properly seated inside the fittings.

Once installed, slowly turn on the water supply and check for any signs of leakage.
What to consider before purchase
Verify the connection sizes (M3/8" and F3/8") match your existing valves and fixtures
Measure the required length to ensure 20 cm is sufficient for your installation
Check the operating pressure of your water system
Ensure the installation environment stays within the 1°C to 90°C temperature range
