Product Details

The COMP Cams 500-1 is a high-performance PTFE (polytetrafluoroethylene) valve stem seal designed for precision sealing in performance and racing engines. This positive seal design controls oil consumption while reducing friction for improved valve train efficiency.

Key Specifications:

  • Valve guide size: .530" (outer diameter)
  • Valve stem diameter: 5/16" (.3125")
  • PTFE construction for superior heat resistance and durability
  • Positive seal design for consistent oil control
  • Compatible with intake and exhaust applications

PTFE valve seals offer excellent chemical resistance and can withstand extreme temperatures, making them ideal for high-performance and racing applications where conventional rubber seals may deteriorate. The precision-machined design ensures proper fitment on .530" valve guides, providing reliable sealing throughout the RPM range while allowing just enough lubrication to prevent valve stem wear.

Note: Price shown is per seal. Verify guide and stem dimensions before ordering to ensure proper fitment.

I ordered a hitch off of this site for Christmas, I have never heard of it nor did I know how they were, but they are great! Got my package in I'd say 4 days, very fast and it was exactly what I wanted! Only down fall was they charged me 3 times and I was short 150$ for a few days. I got my money back and I would definitely order again.

Great Product and excellent service, very fast shipping. I have already told my friends about Autoplicity!!
