LOCTITE® 573™ seals close fitting joints between rigid metal faces and flanges. The product cures when confined in the absence of air between close fitting metal surfaces. Typically used as a form-in-place gasket on rigid flanged connections,e.g. gearbox and engine casings, etc. The thixotropic nature of LOCTITE® 573™ reduces the migration of liquid product after application to the substrate.

For Assembly
1. For best results, clean all surfaces (external and internal) with a LOCTITE® cleaning solvent and allow to dry.
2. If the material is an inactive metal or the cure speed is too slow, spray with LOCTITE® SF 7471™ or LOCTITE® SF 7649™ and allow to dry.
3. Apply a 360° bead of product to the leading threads of the male fitting, leaving the first thread free. Force the material into the threads to thoroughly fill the voids. For bigger threads and voids, adjust product amount accordingly and apply a 360° bead of product on the female threads also.
4. Using compliant practices, assemble and wrench tighten fittings in accordance with manufacturers recommendations.
5. Properly tightened fittings will seal instantly to moderate pressures. For maximum pressure resistance and solvent resistance allow the product to cure a minimum of 24 hours.
For Disassembly
1. Remove with standard hand tools.
2. Where hand tools do not work because of excessive engagement length or large diameters (over 1″), apply localized heat to approximately 250 °C (480F). Disassemble while hot.
For Cleanup
1. Cured product can be removed with a combination of soaking in a LOCTITE® solvent and mechanical abrasion such as a wire brush.
