Encapsulated O-Rings Pharmaceutical Door Seals

Pharmaceutical processes demand consistency, cleanliness, and traceability. At M-Cor, we manufacture encapsulated O-rings designed for high-purity environments where failure is not acceptable. Our seals combine the chemical resistance of FEP or PFA with the elasticity of an elastomer core. The result is a sealing solution suitable for aggressive media, CIP/SIP cycles, and critical containment.

Clean and Controlled Environments

Pharmaceutical systems require materials that perform under strict regulatory conditions.

Our encapsulated O-rings are used in:

Bioreactors
Filtration systems
Filling and transfer lines
Clean-in-place (CIP) systems
Steam-in-place (SIP) environments

Each component is manufactured with attention to surface integrity and dimensional consistency.

Material Compliance and Traceability

We support regulatory requirements with documented material options:

FDA compliant materials
USP Class VI Jacket/ Encapsulation
Lot traceability and documentation
Optional certification and inspection records

Precision Matters in Pharmaceutical Sealing

Encapsulated O-rings are not molded in the traditional sense. They are manufactured using a cut-to-length process, which affects dimensional tolerances.

We address this with:

Measured and documented geometry
Application-specific tolerance review
Optional 100% inspection
