Sanitary Retractable Spring Plungers

With rounded edges and polished surfaces, these spring plungers are free of nooks and crannies where dirt, water, and bacteria could collect. The seal on the base keeps contaminants off the threads and is bright blue, so you can easily spot broken pieces that fall into your line. A tug of the knob manually retracts the nose so you can do everything from positioning containers on an assembly line to locking mixing blades in place. Spring plungers are FDA compliant for direct contact with food.

316 Stainless Steel Nose—Won't corrode from frequent washdowns with harsh cleaners and detergents.

Twist-to-Lock—Free up both hands to adjust your workpiece or switch out parts without the plunger springing back and getting in the way. Pull back the handle and twist to lock the nose in its retracted position.
