Sold as a Case of 24 Bottles

SONLOK 3222 is a fast-curing, low-strength anaerobic thread locking compound designed for bonding and sealing threaded fasteners and retaining small cylindrical parts. Supplied in 50ml bottles with a distinctive purple color, SONLOK 3222 is ideal for applications requiring reliable vibration resistance with easy disassembly. This product is sold as a case of 24 bottles, making it well-suited for production, maintenance, and industrial environments with ongoing usage.

Manufactured by Parson Adhesives, SONLOK 3222 cures in the absence of air when confined between metal surfaces, forming a durable bond that resists loosening from vibration, shock, and thermal cycling. It offers excellent resistance to heat, water, oils, fuels, gases, hydrocarbons, and many industrial chemicals.
