Product Details

The COMP Cams 534-1 Viton Valve Stem Oil Seal is a high-performance replacement valve seal engineered specifically for the GM 6.6L Duramax diesel engine. Manufactured from Viton fluoroelastomer, these seals deliver superior resistance to heat, oil, and chemical degradation compared to standard rubber seals — making them an ideal choice for demanding diesel applications.

Viton material maintains its sealing integrity at elevated operating temperatures commonly found in diesel engines, helping to prevent oil from being drawn down the valve stem and into the combustion chamber. This reduces oil consumption, minimizes blue exhaust smoke, and helps maintain clean combustion.

Key Features:

  • Viton fluoroelastomer construction for outstanding heat and chemical resistance
  • Precision-fit design for the GM 6600/6.6L Duramax diesel engine
  • Helps reduce valve stem oil consumption and oil-related fouling
  • Superior sealing performance over OEM-style rubber seals
  • Direct OEM replacement fit — no modifications required
  • Manufactured by COMP Cams, a trusted name in valvetrain components

COMP Cams Part Number: 534-1. Designed for use with 2001–2005 GM 6600/6.6L Duramax diesel engines. Whether you're rebuilding a high-mileage engine or upgrading to a more durable seal material, the COMP Cams 534-1 delivers professional-grade reliability.

Great prices and fast shipping!

Lightning fast service! Good prices.

Great prices and great products. When it was received, the merchandise was correct and packed well. Thanks, will be ordering oil from this buyer from now on. (order #5647)

Very good prices and good shipping prices. found my parts cheaper then any place else. Thanks to Autoplicity for filling my order #8498 of 4/02/12 quickly and accurately. I will be back.

Fast shipping and saved $60 on a $399 item. However you have to verify your part #'s with the vendor. The part discription on autoplicity sometimes is not what you get. I ordered an item that said it was an O2 plug and bung but when it showed up it was just the bung plug sold separate and customer service basically said it was my bad for not checking for a more accurate discription on the Allstar web site.

Recently ordered a cargo liner and I must say, Autoplicity had the cheapest price anywhere! Excellent communication and super fast shipping! Will definitely do business with Autoplicity again! Thank you for a wonderful shopping experience!

Easy to use website. The belts I ordered didn't have a picture but I knwew what I was looking for.
