To install the hose, ensure the water supply is turned off and the existing connections are clean. Align the M3/8 and F3/8 threaded ends with the corresponding fixture and pipe ports. Tighten the connections manually and then use a suitable wrench to secure them firmly, taking care not to overtighten, which could damage the seals. Once installed, slowly turn on the water supply and inspect the joints for any signs of leakage.
What to consider before purchase
Verify the required thread size for your specific faucet or valve
Measure the distance between connection points to ensure the 50 cm length is sufficient
Check the compatibility of the M3/8 and F3/8 connections with your existing plumbing
Ensure that the hose is not twisted or under excessive tension during installation, as this can compromise the integrity of the connection and reduce the lifespan of the product.
