Cole-Parmer® Disposable 4-Way Stopcocks with Luer Fittings, Polycarbonate

Select from four fluid path configurations with a simple turn of the handle

Stopcocks provide an easy on/off control of your fluid. Four-way stopcocks feature two female Luer fittings and a male Luer fitting with or without a lock. Luer fittings on stopcocks ensure a quick, leak-free connection. Simply turn the handle to a port you want closed; the other two ports remain open. Turn the handle to the side without a port for fluid flow through all three remaining ports simultaneously. Stopcocks are made of polyethylene rotor and transparent polycarbonate body, making it easy to see the flow.
