Additional Information
What is an Encapsulated O-ring?
FEP Encapsulated 'O'-ring seal is an ’O’-ring bound by a seamless and uniform Fluorinated Ethylene Propylene (FEP) encapsulation, which encloses an elastomeric core, completely protecting it from the media. The combination of elastomers and encapsulation choice enables our encapsulated Seals to achieve a combination of temperature, chemical and cost performance unrivalled by Pure elastomeric solutions. The elastomeric core provides the energising sealing force.
Viton®/FKM Inner Core
Delivering greater chemical resistance than Silicone. If the encapsulation is damaged, Viton®/FKM provides greater resilience to chemical attack. This is the choice for LABS Silicone free product.
Technical Data
The FEP encapsulation is the essential component of the Chem-Ring® and it is resistant to practically all chemicals. Within normal application temperatures, FEP resins are vulnerable to only a few chemicals. In some instances, at or near the suggested service limit temperatures of FEP 140°C (284°F) a few chemicals at high concentrations have been reported to be reactive.
Compliance/Certifications
FDA, USP Class VI, EC 1935/2004 & LABS
