CRC locking and sealing agents, 50 ml

CRC Soft Lock, Extra Lock, Rigid Seal and Easy Seal sealants

The CRC adhesives and sealants in this category lock bolts and nuts, seal flanges and bond materials during repairs to machines, vehicles and installations. The category sits under CRC sealants, locking agents and spray glue, the brand's overarching range for these products.

The difference between the locking agents lies in how tight a joint stays afterwards. Soft Lock keeps a thread sealed and secure under vibration, while the bolt can still be loosened at the next service. Extra Lock is the preferred choice where a joint no longer needs to be opened. Easy Seal completes the series as a sealing and locking agent. Each of these products comes in a 50 ml bottle, enough for a large number of joints.

Rigid Seal is a moisture-resistant flange sealant for pumps, covers and housings where you want a flat joint to be leak-tight. Fast Stick is a spray glue in a 500 ml can for quick bonding of light materials. Always apply a locking or sealing agent to clean, dry and grease-free parts, and choose by what the joint has to do rather than by the product name.
