PTFE Coated O-Rings
PTFE coated O-rings are specialized sealing solutions designed to provide low friction and high chemical resistance.
They consist of a core material, typically silicone or Viton®, that is coated or encapsulated with a thin layer of PTFE. This coating enhances the O-ring's performance by reducing wear and friction in dynamic applications while maintaining the core material's inherent properties.
PTFE coated O-rings are ideal for use in demanding environments where operational flexibility and durability are critical.
Standard Durometer and Colors of PTFE Coated O-Rings
PTFE coated O-rings typically have a standard durometer range depending on the core material, commonly ranging from 50 to 90 Shore A. The coating provides a low-friction surface without significantly altering the hardness of the underlying O-ring material.
PTFE coated O-rings are available in a wide array of colors, including but not limited to black, white, red, blue, green, yellow, brown, and clear.
Temperature Range for PTFE Coated O-Rings
PTFE coated O-rings can operate effectively in a wide temperature range, typically from -60°C to +260°C (-76°F to +500°F), making them suitable for both cryogenic and high-temperature applications.
Benefits of Using PTFE Coated O-Rings
PTFE coated O-rings offer excellent chemical resistance, allowing them to withstand exposure to a wide range of aggressive chemicals. The PTFE coating provides a low-friction surface, enhancing the operational flexibility and reducing wear in dynamic applications.
These O-rings maintain the properties of the core material, such as silicone or Viton®, while adding the benefits of PTFE. Encapsulated O-rings, with a PTFE tube covering the core, behave like a high viscous fluid, transmitting pressure evenly in all directions. The availability of various colors and the ability to produce special compounds tailored to specific requirements further enhance their versatility and utility in demanding applications.
Recommended Uses of PTFE Coated O-Rings
PTFE coated O-rings are recommended for use in environments requiring low friction and high chemical resistance. They are ideal for various industries and applications, including:
- Aerospace
- Chemical processing
- Food and beverage production
- Pharmaceutical manufacturing
- Oil and gas
- Semiconductor manufacturing
- Industrial machinery
PTFE Coated O-Rings Applications
Aegis, Aflas, Butyl, Fluorosilicone, Hypalon, or any compound your specific application may require. Coated and Encapsulated O-rings are another option:
- Coated or Encapsulated – Coated O-rings are PTFE coated, with the coating adhering to the O-ring (usually Silicone or Viton®). Encapsulated O-rings are O-rings (usually Silicone or Viton®) covered with a PTFE tube.
- PTFE coating of O-rings is an ideal low-friction coating where operational flexibility is a major consideration.
- The encapsulated O-Ring behaves like a high viscous fluid, any pressure on the seal is transmitted in all directions. Coated O-rings are available in a wide array of colors.
- Special compounds of materials – If you require a specific compound that is not the normal industry standard, we can work with manufacturers to produce that specific compound to meet your needs.
- Mil-Spec, Mil-Std, or Milspecs is a United States defense standard used to achieve standardization objectives by the U.S. Department of Defense. Rockets Seals can source any Mil-Spec through our large network of reputable suppliers.
- FDA food-grade material, foreign designations, USP, KTW, DVGW, BAM, WRAS (WRC), NSF, Underwriters Laboratories (UL), Aerospace (AMS) and Mil-Spec - Rocket has experience with meeting your needs across all industry standards.
