Bondloc B574 Instant Gasket 50ml

Bondloc B574 Instant Gasket is a premium orange anaerobic surface gasket material formulated specifically for sealing close-fitting joints between rigid metal faces and flanges. Engineered to solve the common failures associated with traditional pre-cut cork, paper, and rubber gaskets, B574 cures in the absence of air when confined between mating metal components. The result is a tough, durable unitized assembly that effectively seals against oil, water, coolant, fuels, and common industrial fluids while resisting pressure, thermal expansion, and mechanical vibration.

One of the primary advantages of Bondloc B574 is its thixotropic nature, which prevents the liquid sealant from migrating or dripping after application. This makes it ideal for overhead or vertical flange faces commonly found on gearboxes, engine sumps, differential housings, transmission cases, and heavy-duty pump covers. Because B574 is a liquid compound, it completely fills surface roughness, microscopic imperfections, and machining marks up to 0.5 mm, guaranteeing 100% surface contact between mating faces. This total contact distribution prevents local stress points and eliminates joint movement, which frequently leads to bolt loosening and seal failure in high-vibration applications.

In addition to offering an immediate, low-pressure seal upon joint assembly, Bondloc B574 cures to form a flexible, solvent-resistant plastic barrier. Unlike solid gaskets, it will not shrink, creep, or relax over time, meaning maintenance technicians do not need to periodically retorque flange bolts. Should disassembly ever be required for maintenance or repair work, joint faces can be easily separated using standard hand tools, and cured gasket material can be cleared away using standard solvent cleaners or gasket removers. Whether utilized in automotive maintenance, agricultural machinery repair, or general industrial equipment assembly, Bondloc B574 provides a reliable, professional-grade sealing solution designed to withstand demanding operational conditions.
