Thread: Water tubing

  1. #1

    Default Water tubing

    So I bought some new tubing for my aquacraft up-1 superior but didn’t realize how big it was. It’s OSE Extra large tubing 4mm Inside diameter and 8mm outside Diameter. Will this still work for my boat? The tubing does fit it’s not loose. But on the fittings for the water jacket it’s a bit loose until I pass the part that stretches the hose to seal it.

    The stock tubing is Medium sized. You can use some small zip ties on ALL your connections to take up the size difference.

    Good Luck

    I'd try to replace those fittings with larger. The smallest orifice restricts flow in the entire system.
