Reliable flange sealing with Loctite 574

Practical benefits

Immediate low pressure resistance: You can perform leak testing right after flange assembly because the anaerobic sealant cures quickly without air.
High oil and fluid resistance: You reliably protect engine and gearbox casings against leaks caused by oils, water, and glycol mixtures.
Clean and precise application: The thixotropic formula prevents migration after dispensing, ensuring you achieve a tidy seal without dripping.

In a nutshell

The right choise for

With Loctite 574 Master Gasket flange sealant, you create a reliable seal between close-fitting rigid metal faces and flanges. This anaerobic formula cures in the absence of air and fills gaps up to 0.25 mm. Because it provides resistance to low pressures immediately after assembly, you can leak test gearboxes and engine casings without delay. The thixotropic properties prevent the liquid from running off, ensuring clean and precise application. Highly resistant to oils, water, and glycol mixtures, it prevents fluid leaks and eliminates the need for pre-cut conventional gaskets.
