Harmonization Code : 3506.10.00.00 | Prepared glues and other prepared adhesives, not elsewhere specified or included; products suitable for use as glues or adhesives, put up for retail sale as glues or adhesives, not exceeding a net weight of 1 kg
Main features
- High-Lubricity Thread Assembly
- Immediate Low-Pressure Seal
- Elevated Temperature Fluid Resistance
Product Description
LOCTITE® 592™ is a one-component, medium-strength anaerobic thread sealant designed for locking and sealing metal pipes and fittings. The high-viscosity dimethacrylate ester paste provides high lubricity to help prevent galling during assembly, supports immediate low-pressure sealing, and allows fittings to be repositioned shortly after assembly. After cure, it provides resistance to pressure, vibration, automotive fluids, fuels, water, and elevated temperatures in demanding industrial piping applications.
Key features
- High-lubricity thread sealing: Helps prevent galling on metal pipe threads and fittings during assembly.
- Immediate low-pressure seal: Properly tightened fittings can seal immediately while allowing short-term adjustment after assembly.
- Elevated-temperature fluid resistance: Supports industrial threaded connections exposed to oils, fuels, water, transmission fluid, and temperatures up to 204°C.
