WD-40 490743 Precision Lubricant Pen Pocket Size

Product Description

The WD-40 490743 is a pocket-sized precision applicator pen pre-filled with the classic WD-40 multi-purpose lubricant formula. The pen delivers a controlled, pinpoint flow of lubricant directly to small target areas, reducing waste and overspray compared to aerosol formats. It is well suited for loosening rusted fasteners, silencing squeaky hinges, freeing stuck mechanisms, and protecting metal surfaces from moisture. The liquid formula ranges from light green to amber in color. At 0.96 pounds, the compact form factor fits a tool belt, glove box, or shirt pocket, making it a practical carry item for technicians working across multiple job sites.

This applicator is intended for use in residential and light commercial maintenance settings. It is a strong fit for HVAC technicians, electricians, plumbers, and general maintenance professionals who need precise lubrication in confined spaces where a full aerosol can is impractical. Common applications include lubricating control linkages, hinge pins, threaded fasteners, sliding tracks, and other small mechanical points that require targeted product delivery without excess buildup.

Installation Notes

No installation is required for this applicator pen. Before applying lubricant to any component, power down or de-energize associated equipment and isolate any relevant systems per standard lockout/tagout procedures. Avoid applying lubricant to electrical contacts, rubber seals, or surfaces where petroleum-based products are not rated for use. Remove the cap, position the tip directly at the target area, and apply light pressure to initiate controlled flow.
