• Fitment:Fits for most of the aftermarket cylinder heads that use 11/32" valve stems.
• Size:They are 11/32" stem X .500" diameter.
• High Quality Material:Made from Viton, these seals are a great performance upgrade from factory O-ring style seals.Smaller outside diameter, these Viton seals offer more clearance for performance dual and beehive valve springs.
• Function: The valve oil seal is one of the important parts of the engine valve group, which comes into contact with gasoline and engine oil at high temperatures.The valve oil seal can prevent oil from entering the intake and exhaust pipes, avoid oil loss, prevent the mixture of gasoline and air and exhaust gas from leaking, and prevent engine oil from entering the combustion chamber.
• Machine Work Required - Unlike factory style O-Ring seals that ride on the valve, these seals attach to the guide. Machining of the guide is typically required.
