Stopcocks & Manifolds


Qosina carries an extensive line of stopcocks with 1-, 2-, 3- and 4-way fluid direction and 2-, 3-, 4-, 5- and 6-gang manifolds. Connections include ENFit®, male luer slip, male luer lock, male luer with spin lock, rotating male luer lock, female luer lock and tubing ports ranging from 0.118 inch (3 mm) ID – 0.26 inch (6.6 mm) ID.

Some of our stopcocks are equipped with a needleless injection site, which includes a luer-activated valve that allows for easy control of fluids. Once the stem of a male luer is connected to the female luer lock needleless injection site, the valve opens, allowing for the flow of fluid. Once disconnected, the valve is closed, stopping the flow.

Many of our stopcocks are compliant with the ISO 80369-7 standard. Medical stopcock valve sample kits are available for purchase as well. These kits are ideal for testing because they contain various configurations, pressure ratings, handle rotations, and colors your team can try before investing.
