Hoffman Compression Tubing Clamp
by United Scientific

This Hoffman style pinchcock is made of zinc-plated steel wire, which makes it extremely durable, and also provides resistance to rust and corrosion. It is used for regulating, or severing, the flow of liquids through flexible tubing. Capable of opening up to 1″ wide, it features a hinged lower jaw which allows you to put it wherever you want on the tubing without having to disconnect everything. It is capable of accommodating tubing up to 1″ thick.
