Special engine case and flange sealant

LOCTITE® 574™ 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. It provides resistance to low pressures immediately after assembly of flanges. Typically used as a form-in-place gasket on rigid flanged connections, e.g. gearbox and engine casings, etc.

The thixotropic nature of LOCTITE® 574™ reduces the migration of liquid product after application to the substrate.

The use of Loctite 574 gasket maker or sealant paste is specifically recommended by Porsche on their vehicle line from 1978 onwards for the assembly of engine and transmission components. The use of this sealant paste is of course strongly recommended for earlier Porsche vehicles as well. 

Directions for use

1. For best performance bond surfaces should be clean and free from grease.

2. The product is designed for close fitting flanged parts with gaps up to 0.25 mm.

3. Apply manually as a continuous bead or by screen printing to one surface of the flanges.

4. Low pressures (<0.5 MPa) may be used when testing to confirm a complete seal immediately after assembly and before curing.

5. Flanges should be tightened as soon as possible after assembly to avoid shimming.
