Gibraltar LEP2137-G Straight Ejector Pin 11/32 in Steel

Product Description

The GIBRALTAR LEP2137-G is a straight ejector pin used in injection mold tooling to push finished parts out of a mold cavity at the end of each cycle. Machined from steel with a nitride finish for surface hardness and wear resistance, this pin measures 11/32 inch in diameter with an overall length of 8 inches, a pin length of 7.75 inches, a head diameter of 9/16 inch, and a head height of 1/4 inch. It is sized for applications where consistent dimensional tolerances are critical to mold function and part quality. Toolmakers and mold technicians are the primary installers.

This ejector pin is suited for use in plastic injection molds across both production shop and toolroom environments. The straight pin design is one of the most common configurations in mold base assemblies, fitting ejector pin retainer plates in standard two-plate and three-plate mold constructions. The nitride surface treatment improves resistance to galling and extends service life under repeated cycling. It is sold individually, making it a practical replacement option for worn or damaged pins in an existing mold.

Key Features

• Steel construction with nitride finish for enhanced surface hardness and wear resistance
• 11/32 inch pin diameter for precise fit in corresponding mold plate bores
• 8 inch overall length with 7.75 inch working pin length
• 9/16 inch head diameter and 1/4 inch head height for seating in standard ejector retainer plates
• Straight ejector pin configuration compatible with common mold base layouts
• Sold as a single unit to support targeted replacement without minimum quantity burden

Compatibility

Designed as a standard-dimension straight ejector pin for use in injection mold tooling applications requiring an 11/32 inch diameter pin with an 8 inch overall length. Specific mold base compatibility depends on the bore and retainer plate dimensions of the tooling in use.

Installation Notes

Installation and replacement of ejector pins is performed by toolmakers or mold maintenance technicians. The mold must be fully de-energized, cooled, and removed from the press before any ejector plate disassembly. Pins should be inspected for straightness before installation, as a bent pin can cause mold damage or part defects. Follow the mold manufacturer's procedures for ejector plate reassembly and verify pin travel clearance before returning the mold to production.
