LOCTITE® 128068 is a 1-part, ready-to-use, gel-like anaerobic flange sealant that cures at room temperature when it is isolated from air contact. It is designed to cure slowly to avoid shimming between flanges. It seals close fitting joints between rigid metal faces and flanges and will flex with minor flange movements. Provides resistance to low pressures immediately after assembly of flanges. Typically used as a form-in-place gasket for transmission housings and axle covers.
