from

$33.99
COMP Cams offers a complete line of valve stem seals, from the umbrella seals to the positive-stop Teflon seal.

Whenever you are planning an engine overhaul or a cam change, don’t forget the valve seals.

Product Features:
  • Work with .530″ guides and 3/8″ valve stem diameter
  • Valve stem oil seals keep unwanted oil from entering the combustion chamber
  • Several different types of valve seals are offered
