Zep 652101 Penetrant Lubricant 20 Oz Aerosol

Product Description

The ZEP 652101 is a petroleum-based penetrant lubricant formulated to free seized fasteners, loosen corroded fittings, and displace moisture from metal surfaces. Packaged in a 20 oz aerosol can, it delivers a light brown, low-viscosity penetrating fluid that wicks into tight tolerances between threaded components and mechanical assemblies. The formula contains no silicone or chlorinated solvents, making it compatible with most metals and suitable for use in maintenance environments where silicone contamination is a concern. HVAC techs, plumbers, and mechanical contractors reach for this type of penetrant when breaking loose rusted bolts, freeing stuck valves, or protecting exposed fasteners from further corrosion.

This penetrant lubricant is suited for light industrial and commercial maintenance applications, including HVAC equipment servicing, pipe fitting work, and general mechanical repairs. Typical use cases include loosening corroded condenser fan mounts, freeing seized pipe unions, and treating threaded rod and hardware stored in damp environments. The aerosol delivery format allows directed spray into confined spaces and hard-to-reach assemblies common in mechanical rooms and rooftop units. This product is not rated for food-grade or extreme-pressure applications.

Installation Notes

Applied by licensed HVAC technicians, plumbers, and mechanical maintenance personnel. Before applying to electrical components or near ignition sources, ensure the area is powered down and free of open flame — this product is flammable. Shake the can thoroughly before use and apply in short bursts, allowing dwell time for the penetrant to wick into the joint. Work in a ventilated area and follow all handling requirements outlined on the product SDS.
