Encapsulated O-Rings Manufacturer
Critical seals for critical uptime.
M-Cor Inc. manufactures Teflon® encapsulated O-rings in the USA. In addition,these seals are made with FEP and PFA fluoropolymer jackets and silicone, Viton®/FKM, or specialty elastomer cores.
First, we serve semiconductor, pharmaceutical, bioprocessing, chemical processing, and other high-performance systems. As a result, chemical resistance, dimensional control, and clear documentation are required.
However, most buyers, maintenance teams, and distributors are not high-performance seal experts. They need sealing products that keep equipment running. Therefore, M-Cor focuses on controlled manufacturing, measured parts, and direct support.

Why Engineers Choose M-Cor
M-Cor is a U.S.-based manufacturer focused on precision, repeatability, and engineering-driven sealing solutions. For this reason, we support critical industries where failure is not an option.
- Close-tolerance manufacturing is supported by controlled processes.
- Elastomer extrusion is handled in-house.
- Advanced inspection and measurement systems are used.
- Full traceability and documentation are available.
Supplier Accountability Matters
Many buyers and distributors are not seal experts. Their goal is simple: get the equipment running and keep it running. As a result, M-Cor supports that goal with documented manufacturing, inspection, and certification.
Documented Quality Starts With the Source
At first, a seal can look simple. However, the source behind that seal matters. Therefore materials must be selected, parts must be measured, and inspection records must be controlled.
In addition, clear documentation helps the buyer, engineer, and distributor understand what was supplied. Therefore, M-Cor focuses on traceable manufacturing and practical support.

Encapsulated O-Rings FAQ
What are encapsulated O-rings made of?
Encapsulated O-rings are made with an FEP or PFA fluoropolymer jacket over a silicone, Viton®/FKM, or specialty elastomer core. The clear jacket surrounds the core and provides chemical resistance, while the core provides sealing force and recovery.
Are encapsulated O-rings molded or cut to length?
Most encapsulated O-rings are cut-to-length and welded, not molded. Therefore, their tolerance behavior differs from standard molded rubber O-rings. See: Encapsulated O-Ring Tolerances.
When should encapsulated O-rings be used?
Encapsulated O-rings should be used when chemical resistance, cleanliness, and sealing reliability are critical. They are common in semiconductor, pharmaceutical, bioprocessing, chemical processing, food, and other demanding systems.
