Application & Compatibility

Source application path clues for buyer verification. These are source category/application paths, not confirmed fitment claims:

• CAT > CAT D6G 14G D6D > CAT 3306

This O ring is listed for use in CAT 3306 engines found in D6G and D6D models, as well as CAT 3516B engines in 793 HD trucks. These application paths serve as reference clues for sourcing; they do not confirm universal fitment across all production years or serial numbers. Buyers must verify the specific turbocharger housing type and seal location before ordering. Since no public part number is provided, cross-reference your engine model and vehicle application with technical support to ensure the replacement matches your unit's requirements.

Technical Notes

This O ring functions as a critical sealing component within the turbocharger assembly, preventing oil leaks and maintaining system pressure. Proper installation requires careful handling to avoid deformation or damage to the sealing surface. Inspect the mating groove for debris or wear before fitting the new seal. Ensure the rubber compound matches the operating temperature range of your CAT 3306 or 3516B engine application. Incorrect sizing can lead to premature failure or turbocharger damage.
