Reliable Loctite sealing for rigid flanges

Practical benefits

Instant low pressure seal: You obtain immediate resistance to low pressures directly after assembling your close-fitting rigid metal flanges.
Clean controlled application: The thixotropic formulation prevents unwanted migration of liquid sealant once applied to the component surface.
High chemical resistance: You ensure durable seals on engine and gearbox casings thanks to excellent resistance to oil, water, and glycol.

In a nutshell

The right choise for

With Loctite 574 flange sealant, you seal close-fitting rigid metal flanges quickly and reliably. This anaerobic liquid fills gaps up to 0.25 mm between mating surfaces such as engine blocks and gearbox casings. Thanks to its thixotropic formulation, the sealant stays in place without running, ensuring clean and controlled application. You get instant resistance to low pressures immediately after assembling the components. Once cured, the seal offers high resistance to water, glycol, and oils. This prevents leaks during maintenance, assembly, and overhaul work on rigid cast iron, steel, or aluminum housings.
