Ball Plungers

Ball plungers are the smallest and lightest spring-loaded devise. They feature a ball at the top that lets the device change position quickly and easily. Ideal for both side-load and top-load pressure, the ball rolls within the body, reducing wear on the workpiece or mating part. TE-CO ball plungers are available in press-fit or threaded bodies and in various materials.

Hand-Retractable Plungers

Hand-retractable plungers, also known as quick release plungers, are highly efficient for positioning applications requiring fast, easy installation. Handle styles include a ring, L-handle or knob that disengages the plungers for quick removal or repositioning. Many of our hand-retractable units contain a locking feature that allows the user to “lock” the nose inside the plunger body while indexing their fixtures.

TE-CO offers hand-retractable plungers in several designs, materials and finishes. Body materials are steel, stainless steel, and nose material options include the same, along with Delrin. Hand-retractable plungers are also offered in a threaded and weldable body design.
