Product Details

The COMP Cams 504-1 is a high-quality umbrella-style valve stem seal designed for stock valve guide sizes. This seal features a 3/8" (0.375") valve stem diameter and fits valve guides with a 0.530" outside diameter, making it compatible with a wide range of small block and big block applications.

Key Features:

  • Umbrella-style design provides positive valve stem sealing
  • 3/8" valve stem diameter for common domestic applications
  • Fits stock valve guide size (0.530" O.D.)
  • High-temperature resistant material for durability
  • Helps control oil consumption and reduce emissions
  • Direct replacement for worn or damaged original seals

Umbrella valve seals are a critical component in controlling oil flow to the valve guides. These seals move with the valve stem, creating a dynamic seal that prevents excessive oil from entering the combustion chamber while still allowing proper lubrication of the valve guide. The COMP Cams 504-1 is manufactured from durable materials designed to withstand high engine temperatures and provide long-lasting performance.

Sold individually, allowing you to purchase the exact quantity needed for your engine rebuild or valve seal replacement project.

Great shipping speed great site. Awesome!!! Thanks guys I love my new bumper.

Ordered Sunday and recieved product Tuesday .. What more can u ask for? Great Seller!

The Best Pricing online period! The shipping was very reasonable with great communication and tracking number proviced. My parts were boxed well and arrived right on schedule. This was my first purchase with Autoplicity but will for sure not be my last.

I ordered a bike rack and the rack was shipped promptly, and was exactly what I ordered. Best price on the internet

Had a great first experience with Autoplicity. I ordered my package late in the day on Wednesday and it was at the front door Thursday! Another big plus is that their prices are hard to beat. Won't have a problem ordering from them again!

Found the item I need that was guaranteed to fit my truck. Fast shipping! Liked the paypal checkout!

Product was shipped super fast. And product was in a well packaged box and everything was there. I would do business with them again in the future. Highly recommended and lowest prices!!!
