765JG Generic 3/8 Inch 10mm Water Line Tube Universal Water Filter and Fridge Water Line Part

Code 765JG is a generic 3/8 inch tube, also called 10mm, for water filter and plumbed fridge installs. It is the size commonly used to carry water from an under sink filter to a dedicated tap, or from the supply to a fridge with a dispenser or ice maker. It is stocked on 500 ft rolls, which works out to about 152 metres.

Choosing the right water line tube for a filter or fridge

Water filter systems and plumbed fridges run on small bore tube that pushes into quick connect fittings. Matching the tube size to the fittings is what matters most. A 3/8 inch fitting needs 3/8 inch tube, and a 1/4 inch fitting needs 1/4 inch tube, so check the size printed on your existing tube or fitting before ordering. Replace tube that has gone brittle, cloudy, kinked or split, or that has been cut too short to seat fully, as these cause slow drips and leaks at the joints.

Cutting and connecting the tube

Turn off the water supply before you disconnect any existing line. Cut the tube square with a proper tube cutter or sharp blade, never with side cutters, and check the end has no burrs or flat spots. Push it firmly into the fitting until it bottoms out, then pull back gently to confirm it has locked. Turn the water on slowly and check each joint for drips. Connections to the mains water supply may need a licensed plumber under local rules.

Questions about this part

Is 10mm the same as 3/8 inch?

Not exactly. 3/8 inch is about 9.5mm, and this tube is described as both 10mm and 3/8 inch. Push-fit fittings are made to tight tolerances, so check the size marked on your fitting matches before ordering.
