Loctite 518 Gasket Maker
LOCTITE® 518 is a single-component, medium-strength anaerobic sealant designed as a general-purpose, primerless, semi-flexible, form-in-place flange gasket solution.
Key Features
- Anaerobic Cure Technology - Cures when confined in the absence of air between close-fitting metal surfaces
- Semi-Flexible Design - Adapts to minor flange movements and surface irregularities
- Excellent Contamination Tolerance - Cures even in the presence of minor surface contaminants like oil residue
- Gap Filling Capability - Fills gaps up to 0.25mm (0.010") effectively
- Chemical Resistant Seal - Forms a flexible, solvent-resistant seal that will not tear or decay
- Easy Disassembly - Parts disassemble easily even after extended service
