Sealing Solutions for Automotive Systems
We provide sealing solutions for a wide range of automotive
applications, including:
- Engine systems and power trains
- Fuel and emission control systems
- Hydraulic and braking systems
- Transmission and drive-train components
- Air conditioning and thermal systems
These applications require precision-engineered
seals capable of handling high pressure, temperature and chemical exposure.
Automotive Industry Approvals:
- PPAP AIAG Fourth Edition
- TS 16949 Manufacturing
- APQP
- ASTM D2000 Compounds
- Compounds compatible with High Ethanol content Fuel
Performance Under Extreme Conditions
Automotive sealing components must operate reliably in challenging
environments including:
- High temperatures from engine operation
- Exposure to fuels, oils, and lubricants
- Pressure fluctuations in hydraulic systems
- Continuous movement and vibration
- Materials such as elastomers and PTFE are widely used due to
their resistance to chemicals, temperature extremes and wear.
Effective sealing ensures:
-
Prevention of fluid and gas leaks
- Improved system efficiency
- Reduced maintenance and downtime
- Extended component lifespan
Products for the Automotive Industry
We supply a comprehensive range of sealing products suitable
for automotive applications, including:
These
products are widely used across OEM manufacturing, aftermarket supply and
maintenance applications.
Materials & Compatibility
