• Improves oil control to reduce valve guide wear and oil consumption
• Heat and chemical resistant to withstand harsh engine environments
• Durable construction ensures long service life and consistent performance
• Easy installation with OEM-style dimensions for a secure fit

Construction & Design:

The valve seals feature a PTFE (polytetrafluoroethylene) sealing lip, known for its exceptional chemical inertness and ability to maintain elasticity under high temperatures. This material choice minimizes friction between the valve stem and seal, reducing wear and extending component life. The positive stop design is engineered to limit valve stem movement, preventing the seal from being pushed off or damaged during engine operation.

Manufactured to strict quality standards, these seals provide a precise fit that matches the original equipment dimensions, ensuring reliable sealing and optimal engine performance. Their robust construction makes them suitable for both street and performance applications.

Installation & Fitment:

COMP Cams Positive Stop PTFE Valve Seals are designed for direct replacement on Dodge HEMI engines with 5.7L, 6.2L, and 6.4L displacements. Installation requires standard valve seal removal and installation tools. No special modifications are necessary, making them suitable for professional mechanics and experienced enthusiasts alike. Proper installation ensures a tight seal around the valve stem, preventing oil leaks and maintaining engine efficiency.
