M-Cor Inc. Launches Lathe-Cut Teflon® Encapsulated Gaskets

Since 1987, M-Cor Inc. has been setting industry standards in precision sealing technology. Our latest innovation, the lathe-cut Teflon® encapsulated O-ring, represents a leap forward in design versatility, chemical resistance, and performance. By combining proven materials with advanced manufacturing methods, we deliver sealing solutions that address the most challenging requirements across multiple industries.

What Makes Lathe-Cut Encapsulation Unique

Unlike molded gaskets, which are limited by tooling and cavity constraints, our lathe-cut encapsulation process allows us to create gaskets of virtually any inside diameter—from small precision seals to oversized gaskets for industrial-scale equipment. This process not only eliminates mold tooling costs but also enables faster turnaround times for custom dimensions, ensuring you get a seal tailored exactly to your application.

Premium Material Choices

Outer Jacket Options: Choose FEP for excellent chemical resistance and cost-effectiveness or PFA for enhanced high-temperature performance and superior stress-crack resistance.

Core Material Options: Select silicone for exceptional flexibility and low-temperature sealing, or Viton® (FKM) for high-temperature endurance, outstanding compression set resistance, and broad chemical compatibility

The Key Benefits of Teflon® Encapsulation

Our encapsulated gaskets deliver the best of both elastomers and fluoropolymers:

• Superior Chemical Resistance: Withstands exposure to almost all solvents, acids, and aggressive process chemicals.

• Thermal Versatility: Operates in extreme conditions, from cryogenic temperatures up to 260°C (500°F), depending on jacket choice.

• Durability in Service: Resistant to wear, extrusion, deformation, and cold flow, extending operational life.

• Ease of Use: Low friction surface reduces installation damage, stick-slip issues, and startup failures

.Unlimited Size Possibilities and Cross-Section Options

Because the M-Cor lathe-cut process is free from mold size restrictions, we can manufacture seals for both standard and non-standard applications—making them ideal for large-diameter vessels, semiconductor processing tools, pharmaceutical production tanks, and bioreactors. We offer standard square cross sections as well as select rectangular profiles for specialized sealing environments.

Designed for High-Stakes Industries

Our lathe-cut encapsulated gaskets are engineered to meet or exceed stringent global compliance standards:

• Pharmaceutical & Biotech: FDA compliant, USP Class VI certified, ADI-Free.

• Semiconductor: Manufactured in ultra-clean environments; resistant to acids, plasmas, and solvents.

• Biological & Medical: Non-contaminating, fully traceable, compliant with EU food contact and international safety regulations.
