Casing Material
| Material | Description | Operating Temperature |
| FEP | Copolymer of hexafluoropropylene and tetrafluoroethylene; similar to PTFE but melt-processable for molding & extrusion. | –60°C ~ +205°C |
| PFA | Copolymer of tetrafluoroethylene and perfluoroethers; clear, durable, and performs better at high temperatures. | –60°C ~ +260°C |
Core Material
Encapsulated O-rings use a rubber core made from Fluorocarbon (FKM) or Silicone (VMQ).
Both solid and hollow designs are available — hollow cores provide greater flexibility and lower compression force.
Features
- Durable & Wear-Resistant: Longer lifespan than standard rubber O-rings.
- Chemical Stable: Resistant to most chemicals, with exceptions for alkali metals, fluorine, and certain halides at high temperatures.
- Rubber-Like Elasticity: Maintains flexibility for reliable sealing.
- Low Friction & Gas-Tight: FEP/PFA surface has very low friction (0.1–0.2) and excellent gas barrier properties.
- Suitable for Harsh Environments: Performs well under extreme temperatures, pressures, and aggressive media.
Application
- Pumps and Valves
- Heat Exchangers
- Filters
- Pipelines
- Gas Compressors
Specifications
Encapsulated O ring is produced via extrusion, allowing for almost any diameter and cross-section with greater flexibility than fully molded O-rings.
