Product Details

The COMP Cams 522-1 is a precision-engineered valve stem seal designed for high-performance and racing engines. This seal features a durable metal body construction with a Viton (fluoroelastomer) sealing element that provides superior heat resistance and oil control compared to standard rubber seals.

Key Specifications:

  • Valve guide outer diameter: .530 inches
  • Valve stem diameter: 3/8 inch (.375 inches)
  • Metal body construction for dimensional stability
  • Viton sealing material withstands temperatures up to 400°F
  • Positive seal design prevents oil migration down valve stems

Viton valve seals are essential for controlling oil consumption in performance applications where cylinder head temperatures exceed the capabilities of standard seals. The metal body maintains precise fitment even under extreme thermal cycling, while the Viton element provides a long-lasting seal against the valve stem. These seals are commonly used in rebuilt cylinder heads, performance engine builds, and racing applications where reliability and oil control are critical.

Sold individually. Verify guide and stem dimensions before ordering to ensure proper fitment.

The magnaflow kit that I ordered was about $100 cheaper than any other site I could find. Shipping was fast, and relatively cheap too.
