Product Details

The COMP Cams 506-1 is a high-performance valve stem seal engineered for precision sealing in demanding engine applications. This seal features black Viton construction, providing exceptional heat resistance and durability compared to standard rubber seals.

Key Specifications:

  • Guide Size: .494" (12.55mm) - fits standard valve guides
  • Valve Stem Size: 11/32" (.344") - compatible with most performance and stock replacement valves
  • Material: Black Viton for superior temperature resistance and longevity
  • Positive valve stem sealing to control oil consumption
  • Prevents excessive oil from entering the combustion chamber

Viton valve seals are the preferred choice for high-performance and racing applications due to their ability to withstand elevated temperatures without hardening or cracking. This seal provides reliable oil control while allowing proper valve guide lubrication, making it suitable for both street and track use.
