Product Details

The COMP Cams 503-12 valve stem seal set provides reliable oil control for high-performance and racing engines. These positive valve stem seals are precision-engineered to fit .530" valve guide outer diameter and 11/32" (.344") valve stem diameter applications.

Key Features:

  • PTFE (Teflon) construction for superior heat resistance and durability
  • Positive seal design prevents oil from entering the combustion chamber
  • Fits .530" valve guide outer diameter
  • Compatible with 11/32" (0.344") valve stem diameter
  • Set includes 12 seals for complete V6 or inline 6-cylinder engines
  • Ideal for performance rebuilds and race applications

COMP Cams valve stem seals are designed to withstand extreme temperatures and high RPM operation while maintaining consistent sealing performance. The PTFE material offers excellent chemical resistance and low friction properties, reducing wear on valve stems during operation.

Quick, easy, and great prices

Easy

I ordered a truck bed cover and Autoplicity had the lowest price I could find. I was a bit concerned that the delivery time might be longer than from other suppliers but to my surprise it arrived in just over a week. Customer service was good too. They answered all the questions I had about my order prior to shipment.

Quick and easy. No problem at all. Would recommend them.

Great Experience, product as described, quickly shipped.

Cool

easy and quick

Recieved but not installed in car yet so i cant really know for sure if im completely happy or not.

Best prices, Super fast shipping!

Prices are among the lowest around. Had a change with my order. Customer support team was quick to respond to emails and make corrections. Will order from Autoplicity again.

After weeks of shopping around, I was able to find the best price from Autoplicity. The ordering process was very simple since I had the option to pay through my Amazon account. Great experience.

These guys have the best prices available online. There customer service is on point as well.

Just placed order; seems ok so far
