When your operation cannot afford leakage, downtime or long lead times, Chem-Ring® Encapsulated 'O'-rings offer a practical solution for chemical resistance and consistent sealing force. Vulcan Seals’ Chem-Ring® FEP/PFA Encapsulated O-rings combine a protected elastomer core with a seamless fluoropolymer jacket. Backed by extensive stock and global support, they help to ensure that your production continues to run smoothly.
For chemically demanding applications or where regulatory compliance is non-negotiable, an encapsulated 'O'-ring can be a valuable specification upgrade. Chem-Ring® Encapsulated O-ring designs use seamless FEP or PFA encapsulation around an elastomeric core (silicone or Viton™/FKM), meaning the media comes into contact with the fluoropolymer while the core provides the energising sealing force.
