Anaerobic Threadlocker CX80 RC-43, 50 ml bottle, brand CX80

Anaerobic threadlocker CX80 RC-43 in a 50 ml bottle is a liquid adhesive formulated to lock and seal metal threaded fasteners. It cures when confined between close-fitting metal surfaces in the absence of air, forming a durable polymer that resists vibration-induced loosening and helps prevent leakage at threaded joints. The product is intended for mechanical assemblies, repair and maintenance tasks where secure fastening and sealing of nuts, bolts and cylindrical fittings are required.

Advantages

This threadlocker provides reliable prevention of loosening under vibration and dynamic loads, while also offering sealing properties to reduce fluid or gas leakage at threaded connections. The liquid consistency allows for easy application to small and medium-sized fasteners, and the formulated cure produces a strong bond on metal-to-metal contact without the need for external heat. It is suitable for use in maintenance operations where downtime and rework must be minimized.

Suitable for

• Locking nuts and bolts in machinery and equipment
• Sealing threaded cylindrical fittings and couplings
• Preventing loosening of fasteners exposed to vibration
• Maintenance and repair of automotive and industrial assemblies

Key specifications

• Form: liquid anaerobic adhesive supplied in a 50 ml bottle
• Curing mechanism: cures when confined between close-fitting metal surfaces in absence of air
• Application surface: designed for metal-to-metal threaded connections
• Performance: provides anti-vibration locking and sealing of threaded joints

How to use

Ensure mating threads are clean, dry and free of oil, grease or loose debris before application. Apply a small amount of threadlocker onto the male threads or into the female thread, then assemble and tighten to the required torque. Allow the adhesive to cure while the assembly is confined; full handling strength is achieved after the recommended cure period depending on gap size and substrate. For disassembly after curing, follow proper procedures for heated or mechanical removal if required.

Usage recommendations

Use on clean metal threads only; avoid application to plastics or coated surfaces unless compatibility is confirmed. Store the bottle upright in a cool, dry place and keep the cap tightly closed when not in use to maintain product performance. For critical or high-temperature applications consult technical guidance to ensure suitability.
