High Performance Engine Seals

High performance PTFE lined engine seals for superior operation in harsh environment and high temperature applications. Custom designed to your requirements.

• Typical Surface Speed: 76m.s-1
• Max Operating Temperature: 230ºC
• Pressure Range: -0.86 to +5 Bar(g)
• Fluid Compatibility: Any
• Lip Configuration: Custom Designed

Race-Tec High performance engine seals use a PTFE (Teflon®) element which chemically bonded to the elastomer sealing lip. Offering superior life and performance to seals with a sprayed/dipped PTFE coating. When compared to other types of PTFE seals using single or multiple PTFE wafers, our hybrid PL technology offers a more flexible solution for high-speed shaft dynamics.

The elastomer section of the seal is chemically bonded to the housing during the moulding process. This allows our seals to be bonded directly to complex housings using exotic materials to save space and weight.

The reliability and performance of our engine seals has enabled to be in the position where our products are used in engines ranging from high performance F1, Nascar and Le Mans, through all forms of motorsport to smaller engines of Kart and Scooter racing.
