Gibraltar SPR25A-PT-G Pull Ring Plunger 1/4-20 Ss

Product Description

The GIBRALTAR SPR25A-PT-G is a stainless steel pull ring plunger designed for use in indexing, positioning, and locking applications across mechanical assemblies. The plunger features a 1/4-20 thread and a 0.31-inch thread length, making it straightforward to install into pre-tapped housings. With an initial end force of 0.5 lb and a final end force of 2 lb, it provides a controlled, repeatable spring-loaded engagement suitable for light-duty panel, fixture, and jig work. The pull ring allows manual retraction without tools. This part is typically installed by maintenance technicians, machine builders, and mechanical assemblers working on equipment requiring adjustable or removable stop points.

This spring plunger is suited for use in industrial machinery, precision fixtures, tooling jigs, enclosures, and positioning assemblies where a retractable stop or detent is required. The non-locking plunger type allows the plunger tip to rotate freely, reducing wear in applications where the mating surface may move laterally. The pull ring provides an accessible grip point for manual retraction in confined installations. It is appropriate for both OEM build applications and field service replacement scenarios.

Key Features

• 1/4-20 thread with 0.31-inch thread length for standard tapped-hole installation
• Non-locking plunger type allows free rotation of the plunger tip
• Pull ring design enables tool-free manual retraction
• Spring end force range of 0.5 lb initial to 2 lb final for light-duty detent applications
• Stainless steel construction resists corrosion in washdown or humid environments
• Compact body length of 0.44 inches suits tight-clearance assemblies

Compatibility

Designed as an OEM-style replacement or new-installation spring plunger for mechanical assemblies requiring a 1/4-20 threaded pull ring plunger with non-locking action and stainless steel construction.

Installation Notes

Installation requires a pre-tapped 1/4-20 hole in the mating component. Use a 0.25-inch hex wrench to seat the plunger body to the appropriate depth. Ensure the housing material is rated for the thread engagement required and that the plunger tip aligns with the mating detent surface before final tightening. De-energize or secure any moving equipment before servicing assemblies that contain spring plungers.
