Loctite® 5800 is a medium-strength, thixotropic anaerobic sealant designed for gasketing applications between rigid metal flanges. It cures in the absence of air between close-fitting metal surfaces, forming a durable seal that resists low pressures immediately after assembly. Notably, it carries no hazard symbols, risk phrases, or safety phrases, making it a health and safety-friendly choice for various industrial applications.

Loctite® 5800 is a single-component, medium-strength anaerobic sealant formulated for sealing close-fitting joints between rigid metal faces and flanges. Upon application, it cures at room temperature when confined in the absence of air, forming a flexible, chemical-resistant seal. Its thixotropic nature ensures easy application and reduces the risk of sealant migration after application. This product is typically used as a form-in-place gasket on rigid flanged connections, such as gearbox and engine casings. The absence of hazard symbols and safety phrases in its formulation underscores its commitment to user safety without compromising performance.
