Solid-Core and Hollow-Core Designs

Teflon® encapsulated O-rings are supplied with either solid or hollow-core energizers. Specifically, solid-core energizers provide the best resistance to compression set and recovery. In contrast, hollow-core (tubing) O-rings, containing a circular gap within the energizer, offer effective sealing for situations requiring a more flexible, easier-to-squeeze O-ring. Additionally, our standard product is solid-core; however, hollow-core is available by request. See Compression Set Blog

 

 

We can also extrude custom shapes such as square, rectangular, and D-shaped profiles. Minimum order quantities apply.

 

 

Lock Out Corrosive Fluids and Gases: Teflon® Encapsulated Silicone and Viton® O-Rings

M-Cor’s PTFE encapsulated O-rings feature a core made of silicone, Viton, or EPDM elastomers, all encased in a uniform Teflon sheath. Therefore, this combination allows the O-rings to maintain their shape under pressure and offer chemical resistance against a variety of acids, bases, and solvents. Furthermore, these O-rings have low friction, non-stick surfaces, minimal gas release, and very low water absorption. In addition, they provide excellent electrical insulation properties and durability, operating effectively over a wide temperature range. Therefore, they are essential in applications requiring protection against corrosive substances. These O-rings are also referred to as FEP encapsulated O-rings, PFA encapsulated O-rings, Silicone encapsulated O-rings, and Viton® encapsulated O-rings. For more details, see the Physical Properties page.

 

Teflon® Encapsulated O-Rings: Overview

Encapsulated O-rings feature a seamless Teflon® jacket surrounding a rubber core, available in Silicone, Viton®, and EPDM. This design provides chemical inertness and resistance to compression set, making them ideal for harsh sealing environments. We stock Teflon® encapsulated O-rings in cross sections from .060 to .750 inches, covering all AS568 sizes from AS009, preferred metric sizes, and JIS, with larger custom sizes available upon request. PTFE Encapsulated o-rings for chemical resistance, these encapsulated  o-rings resist most industrial solvents, acids, and corrosive materials.

Installation Guidelines

The FEP/PFA encapsulation is a hard material with limited flexibility compared to the fully elastomeric O-ring inside. Accordingly, for difficult installations to avoid damage heat the Teflon® encapsulated O-rings prior to installation and ensure installation surfaces are free from sharp edges.,

Heating Methods:

  • Hot Water (Recommended): Heat water to 100°C / 212°F, place Teflon® encapsulated O-rings in water for a minimum of 3 minutes, and install them while still warm.
  • Oven Heating: Set oven to 100°C / 212°F, heat Teflon® encapsulated O-rings for a minimum of 15 minutes, and install them immediately after removing from the oven.

Industrial Applications

M-Cor Inc.’s Teflon® encapsulated O-rings can be utilized in a wide range of industries, including:

  • Chemical Process Industries
  • Pharmaceutical Production
  • Polymer Production
  • Paint & Coating Operations
  • Foodstuff Industries
  • Petrochemical Industries
  • Chemical Transport
  • Semi-Conductor Manufacturing

     

Conclusion:

 

In summary, M-Cor Inc’s Teflon® Encapsulated O-Rings are versatile solutions for a variety of industries. Not only do they offer high chemical resistance, but they also provide broad temperature ranges and mechanical properties. Moreover, their durability and adaptability make them suitable for a wide range of applications, ranging from medical equipment to challenging chemical processing tasks. Consequently, these O-rings stand out as a reliable choice for demanding environments. Ultimately, their exceptional performance characteristics ensure long-lasting effectiveness across diverse sectors.

 

 

 

While laboratory testing of M-Cor’s ENCAP-O-SEAL™ o-rings is  a valuable screening technique, the final selection for use in applications  must be based on functional evaluations or experience under actual  end use conditions. This has become industry practice dictated by  the many complex aspects of performance in severe conditions
