Perfect Circle Seals

AValve Stem Seals
If you've been frustrated by the limitations of trying to fit a single valve stem seal solution to all your engine designs, you'll appreciate the choices you get at Dana Corporation. From our selection of six valve stem sealing configurations, you'll find the optimum design for your application. Choose from two catagories - Integral or Guide Mounted.

Metering the proper amount of oil to the valve stem and guide is the most important function of a valve stem seal.  Every Dana valve stem seal design is evaluated on our oil metering test machines to optimize valve train durability, oil consumption, and emissions. With engineering, sales, and manufacturing teams centrally located,  Dana works with your engineers to understand the application and offer you a customized solution:

  • Precise oil flow rate
    - Low flow for emissions-sensitive applications
    - Higher flow for guide and stem wear reduction
