Metcar mechanical seal rings and seal faces are manufactured using highly engineered carbon-graphite materials for demanding high-speed or high-load applications. The seal rings are ideal for sealing liquids, such as water, hot water, acids, alkalis, fuels, heat-transfer fluids, liquefied gases, solvents and beverages. Metcar seals can also be used for gases, and are available in several grades. Antimony-impregnated grades offer excellent self-lubricating properties. Nickel-chrome-impregnated grades are favored for high-pressure, liquid-lubricated seals because of their high modulus of elasticity and high tensile strength. Metcar grades with special film-control additives are used to reduce the wear rate of seal rings running in humid air, dry nitrogen and vacuum. Metcar seals are manufactured according to customer-supplied drawings. — Metallized Carbon Corp., Ossining, N.Y.
