Loctite LOC1335868 243 Medium Strength Oil Tolerant - 250ml

Loctite 243 Medium Strength Threadlocker, Oil Tolerant, 250ml (LOC1335868)

Loctite® 243 is a medium-strength threadlocking compound designed for locking and sealing threaded fasteners that may require normal disassembly using standard hand tools. Ideal for preventing loosening and leakage, it protects fasteners from shock and vibration in demanding applications.

The product cures in the absence of air when confined between close-fitting metal surfaces, delivering reliable and consistent performance. Formulated from methacrylate, it provides robust curing and features a thixotropic consistency that reduces product migration after application.

Loctite 243 performs effectively on both active metals (such as brass and copper) and passive substrates including stainless steel and plated surfaces. Its high-temperature performance and oil tolerance allow it to cure even where minor surface contamination is present, including cutting oils, lubricants, anti-corrosion, and protective fluids.
