Extra large bore high flow threaded connectors allow for faster delivery of viscous fluids and avoid the risk of connection errors between incompatible fluid systems. The extra large bore threaded male connector (part #98663) and female connector (#98633) are composed of ABS, have a 6 mm OD, and are 1.5 in. in length. The 5 mm large, 6 mm extra large, and 8 mm super large bore threaded connectors will only mate up to each other and not to standard luers. All connectors are available in custom colors for an additional charge.
