Stainless Steel Spring Plungers
Jergens Spring Plungers, unlike conventional spring plungers, are machined in one piece. The spring is assembled from the top so that there is no need for a set screw. Our Spring Plungers do not have a set screw that can loosen or separate from the plunger body. The advantage is no lost springs and no need for “easy-out” tools. When adjusting Solid Drive, you can be sure the plunger body is turning and not a set screw.
Features & Benefits:
-
Single-unit construction for better reliability
- No set screw to separate from the plunger body

Material Specifications:
-
Body Material: 303 Stainless Steel
-
Tip Material: 303 Stainless Steel

-
Black = Steel Tip, Heavy Force
-
