Metcar’s Grade M-444 mechanical seal primary rings for sealing refrigerants and other low viscosity liquids offer self-polishing characteristics and dimensional stability. It is the self-polishing characteristic of the M-444, antimony impregnated, carbon-graphite material and the high dimensional stability of both solid silicon carbide and antimony impregnated carbon-graphite that enables these two materials to run in close proximity. According to the company, ordinary mechanical seals with resin impregnated, carbon-graphite primary rings do not have the self-polishing characteristic or the dimensional stability necessary for sealing low viscosity liquids.
