Fluid transfer couplings use non-drip technology to make easy connections with minimal air inclusion. Stainless steel or plated brass designs are rated from vacuum to 20 bar and from -20° to 315° C. They come in many end configurations, with double or single valve construction, or a straight-through, valveless design. Color-coded rings and ball and groove key combinations ensure fluid lines are never contaminated. Sizes are available to 1 in.
