Short Spring Plungers – Steel with Delrin® Nose

Spring-Loaded Devices

Self-contained plunger-and-spring device available in many sizes and forces. Short Spring Plungers have a shorter overall length, and shorter stroke, than our standard Spring Plungers. Available in the four versions shown below. Made in USA.

Install and/or adjust from either end. When using the slot at the plunger end to install, use a Plunger Wrench instead of a screwdriver to avoid over-compressing the spring (see Related Products below). A thread-locking element holds the unit securely in place after installation.
