Dart Valve Stem Seals

4.91 out of 5 stars 11 Customer Reviews

Dart valve stem seals are designed to control the lubrication of the valve stem as it slides in the valve guide. Too little oil causes stem and guide wear. Too much oil increases oil consumption and can cause a buildup of carbon, leading to valve seat damage and an early valve grind. Available in different styles and sizes, Dart valve stem seals are just what you need to take control of your oil.
