Product Details

COMP Cams umbrella valve seals are engine valve stem oil seals. They keep unwanted oil from passing through the valve guide clearance and entering the combustion chamber. They are a replacement option for engines that use stock, unmodified valve guides.

Key Features:

  • Umbrella-style design: This style is normally used when a larger-than-stock diameter valve spring is installed.
  • Stock guide size: The seals are made for OE-size valve guides and typically need no machine work.
  • Oil control: The seals help limit oil consumption and exhaust smoke caused by oil getting past the valve guides.
  • Rubber construction: The seals are made of rubber.
  • Made by COMP Cams: COMP Cams is a well-known name in camshafts and valvetrain components. It also offers O-ring, positive-stop PTFE and Viton seals for other spring and guide setups.

Choose the variant that matches your valve stem diameter and the number of seals you need. These seals are a simple way to refresh the valve stem sealing when rebuilding or upgrading an engine's valvetrain.
