COMP Cams offers a complete line of valve stem seals, from the umbrella seals to the positive-stop Teflon seal. These seals are a must to keep unwanted oil from entering the combustion chamber through the clearance in the valve guides. We also have a smaller diameter Viton seal available for triple spring applications. Whenever you are planning an engine overhaul or a cam change, don't forget the valve seals.
Providing the best sealing properties and spring clearance, viton valve seals are an excellent choice in performance applications. These 529 seals have a .675" OD and fits applications with 11/32" valves and .530" OD guides.
Available individually under 529-1.
