Short Spring Plungers with Extended Travel and Delrin Nose

Spring-Loaded Devices

Self-contained plunger-and-spring device available in a wide range of sizes. Short Spring Plungers with Extended Travel have the body length of a Short Spring Plunger while providing the longer stroke of a standard Spring Plunger (but are available only with light spring force). Available in the four versions shown below. Made in the 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.
