Loctite LOC51221 Penetrating Oil 12 Oz Aerosol

Product Description

The LOCTITE LOC51221 is a penetrating oil in a 12 oz aerosol can, formulated to loosen frozen, corroded, or seized fasteners and components. Penetrating oils work by wicking into tight thread gaps and between mating surfaces, displacing moisture and reducing friction so stuck bolts, nuts, and fittings can be broken free without damage. This product ships as an individual can and is sized for field and shop use by HVAC technicians, plumbers, electricians, and general maintenance professionals who regularly encounter corroded hardware in aged systems.

LOC51221 is suited for a wide range of service scenarios: loosening rusted pipe unions and galvanized fittings, freeing seized electrical conduit connectors, breaking loose corroded HVAC cabinet screws, or releasing stuck blower wheel set screws. The aerosol delivery format allows targeted application in tight spaces where a drip bottle cannot reach. It is appropriate for both residential and light commercial maintenance work.

Installation Notes

Apply to affected fasteners and allow adequate dwell time before attempting to break the joint loose.
