O-Rings for Chemical Processing & Storage
High-performance sealing solutions engineered to withstand aggressive chemicals, extreme temperatures, and demanding process conditions while preventing leaks and contamination.
Critical Performance Requirements
- Chemical Compatibility: Resistance to acids, bases, solvents, and aggressive process media
- Extreme Temperature Stability: Performance from cryogenic to high-temperature processes
- Low Permeability: Minimize permeation of volatile chemicals
- Purity Standards: Non-contaminating for pharmaceutical and food-grade applications
- Long-Term Stability: Maintain properties after prolonged chemical exposure
- FDA/USP Compliance: Where required for regulated industries
Key Applications
- Chemical Reactors: Sealing agitator shafts, manways, and ports
- Pump Systems: Seals for chemical transfer and metering pumps
- Valve Seals: Ball valves, diaphragm valves, and control valves
- Storage Tanks: Sealing access points and connections
- Pipeline Systems: Flange seals and expansion joints
- Pharmaceutical: Bioreactors and sterile processing
