1. Spring Energized PTFE Seal for Extreme Industrial Demands
The PTFE Spring Energized Oil Seal is specially designed for critical sealing under extreme conditions. The internal spring applies continuous radial force, ensuring a reliable seal even under fluctuating pressure, vibration, and shaft misalignment. PTFE offers low friction and outstanding resistance to heat, chemicals, and wear, making this seal ideal for hydraulic machinery, pumps, and actuators in industrial environments.

 

2. FKM & NBR Rubber Compatibility for Diverse Media
This seal is available with FKM (Viton) or NBR (Nitrile Rubber), depending on your application’s chemical and temperature requirements. FKM is perfect for high-temperature and aggressive chemical media, while NBR offers excellent performance in oil-based hydraulic systems. Combined with the PTFE sealing ring, these materials enhance durability, media compatibility, and overall sealing effectiveness in hydraulic machines, rotating shafts, and linear actuators.

3. Leak-Free Performance and Reduced Maintenance
Spring energized seals offer extended service life by compensating for wear, pressure variations, and thermal expansion. This leads to lower maintenance requirements and reduced equipment downtime. These PTFE spring seals are particularly effective in systems where traditional elastomeric seals would degrade quickly, making them a cost-effective solution for OEMs, repair operations, and hydraulic machinery manufacturers.

 

 

Frequently Asked Questions (FAQ)

Why does my CFKS oil seal fail prematurely? Common causes and prevention tips2025-06-26T15:44:39+08:00

Premature oil seal failure can result from improper installation, poor shaft finish, incorrect material selection, or excessive pressure. To prevent this, ensure the shaft surface is smooth and within tolerance, use correct tools during installation, and choose seals made from materials compatible with your media and temperature.

How to correctly install a CFKS industrial oil seal to avoid leakage2025-06-26T16:04:32+08:00

Always clean the shaft and bore before installation. Use appropriate seal drivers to avoid deformation. Lubricate the lip before fitting to reduce friction during the first rotation. Ensure the seal is seated evenly and not tilted to avoid leaks.

What to do when your CFKS hydraulic seal is leaking under pressure2025-05-20T16:33:14+08:00

Check if the pressure exceeds the seal’s rated limit. Examine for wear, hardening, or improper installation. Replace the seal if damaged, and consider upgrading to a high-pressure CFKS seal variant. Also, verify that the housing and shaft are properly aligned.

How to choose the right CFKS oil seal for extreme operating environments2025-05-20T16:34:39+08:00

For high temperatures, aggressive chemicals, or abrasive environments, choose CFKS seals made of FKM, PTFE, or high-performance elastomers. Consider using seals with protective dust lips or metal casing. Our team can recommend the best fit for your application.
