LOCTITE 518 is a medium-strength sealant which cures when confined in the absence of air between close-fitting metal surfaces. Typical applications include sealing close-fitting joints between rigid metal faces and flanges. Provides resistance to low pressures immediately after assembly of flanges. Typically used as a form-in-place gasket on rigid flanged connections, e.g. transmissions and engine casings. Max. gap size: 0,3 mm Service temperature range: -55 to +150 degrees C Tensile shear strength in N / mm 7.5
