Gibraltar PR25A-G Pull Ring Plunger 1/4-20 Steel

Product Description

The GIBRALTAR PR25A-G is a steel pull ring plunger designed for indexing, positioning, and light-duty locking applications in mechanical assemblies. The plunger uses a non-locking design with a pull ring for manual retraction without tools. It threads into a tapped hole using a standard 1/4-20 thread and delivers an initial end force of 0.5 pounds and a final end force of 2 pounds, making it well-suited for light positioning work where repeatable, spring-loaded engagement is required. Machinists, maintenance technicians, and machine builders install these plungers in fixtures, jigs, panels, and equipment enclosures.

This pull ring plunger is used in industrial machinery, fabrication fixtures, control panel assemblies, and tooling setups where a manually retractable spring plunger is needed. The pull ring allows the plunger to be retracted by hand without a separate tool, streamlining operation in repetitive positioning tasks. It is a direct-install component suited for both OEM assembly and field maintenance on equipment requiring 1/4-20 threaded plunger positions.

Key Features

• Non-locking pull ring design allows tool-free manual retraction
• 1/4-20 thread for installation into standard tapped holes
• Steel construction for durability in mechanical assembly applications
• Initial end force of 0.5 pounds to final end force of 2 pounds for light positioning loads
• Compact body length of 0.44 inches suits space-constrained assemblies
• Hex drive head for installation and torque control with standard tools

Compatibility

Designed for use in any mechanical assembly or fixture requiring a 1/4-20 threaded non-locking spring plunger with a pull ring for manual retraction.

Installation Notes

Installation is performed by maintenance technicians, machinists, or assemblers using a standard wrench or hex key on the 0.25-inch hex head. De-energize or lock out any associated equipment before installing or replacing plungers in live machinery per applicable LOTO procedures. Do not overtighten; thread engagement into the tapped hole should be confirmed before applying final torque. Ensure the mating bore is clean and free of debris to allow full plunger travel.
