Cole-Parmer® Disposable 2-Way, 3-Port Stopcocks with Luer Fittings, Polycarbonate

Restrict your flow to only two directions with the 2-way, 3-port stopcocks

Stopcocks provide an easy on/off control of your fluid. Two-way, three-port 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. The handle can only be turned to the "off" position at the male Luer port or female side Luer port. Stopcocks are made of polyethylene rotor and transparent polycarbonate body, making it easy to see the flow.
