SHORT SPRING PLUNGERS
WITH EXTENDED TRAVEL

 


Steel




Stainless Steel


 
FEATURES: These Spring Plungers have the body length of a Short Spring Plunger while providing the longer stroke of a standard Spring Plunger (spring force is somewhat reduced). This self-contained plunger-and-spring device is available in a wide range of sizes. Locking element holds the unit securely in place after installation. Install and/or adjust from either end (when using the slot at the plunger end, install with a Plunger Wrench to avoid over-compressing the spring). Available in steel, with a hardened plunger nose, or stainless steel. Made in USA.
