Vibra-Tite® 548
Retaining Compound
September 2012
Product Description
Vibra-TITE 548 is a medium viscosity, quick curing,
high strength anaerobic retaining compound. VibraTITE 548 is used for tight-clearance, and slip-fit
metal applications. The product performs on
aluminum, steel, plated, stainless steel, and special
alloy parts. Vibra-TITE 548 exhibits good
temperature and solvent resistant. Vibra-TITE 548
can be used to create an air-tight seal on cylindrical
assemblies. This product cures rapidly on all metal
surfaces.
