Introduction
WEIDUN quick-disconnect fueling joints consist of two main types: U-end fueling joints and T-end fueling joints. All models adopt a uniform 3/4 Inch NPT thread standard. Different colors are applied to distinguish fluid media, paired with exclusive keyed structures. Joints of different colors within the same series are non-interchangeable, which structurally avoids cross-contamination of oils and fluids. They are suitable for crankcase refueling applications of various mechanical equipment.
