    Viton seals provide better sealing to keep oil out of combustion chambers for improved engine efficiency and performance

    Proper lubrication of moving components is vital to engine life, especially in high performance engines. Viton valve stem oil seals have gained quite a reputation for keeping oil in the proper places and out of your engine's combustion chambers. COMP Cams now announces a major expansion of its Viton Metal Body Valve Stem Oil Seal line, providing more versatility and sealing efficiency for engine builders looking for just the right seal, especially where inner valve spring clearance is an issue.

    COMP Cams Viton Metal Body Valve Stem Oil Seals are available for 5/16, 11/32 and 3/8-inch diameter valves in a wide range of outside diameters from 0.677-inch through 0.547-inch. This allows the usage of small inside diameter valve springs. They are also available for either 0.500-inch or 0.530-inch OD valve guides. Viton seals, which use a proprietary fluoroelastomer material, are extremely resistant to heat, oil additives and abrasion. The metal body ensures the seals remain in place and deliver excellent long-term durability. A precision seal installation tool is available 555-80596

    Features:
  • More Versatility & Sealing Efficiency
  • O-Ring & Umbrella Seals Require No Machining
  • Metal Body Ensures the Seals Remain in Place
  • Long-Term Durability
