About this part

Product Details

These COMP Cams valve seals are made from PTFE, a material known for its low friction and resistance to heat and chemicals. They're designed to fit valve stems that are 5/16 inches in diameter and valve guides that are .500 inches in diameter, with a seal outer diameter of .600 inches. This specific design choice gives you more clearance, especially when you're running double valve springs, which is something you often see in performance builds.

Unlike basic umbrella or O-ring seals, these PTFE seals offer a more positive seal to keep unwanted oil from getting into your combustion chambers. Keeping oil out of the combustion area is crucial for preventing issues like blue smoke from the exhaust, fouled spark plugs, and reduced engine performance. This set includes 16 seals, enough for a typical V8 engine.
