Qnity™ Kalrez® O-rings, Seal That Survive Extremes
In industries like Oil & Gas and Pharmaceuticals, sealing failure can lead to downtime, safety risks, and product loss. Extreme temperatures, aggressive chemicals, and high-pressure conditions demand sealing solutions that go beyond conventional materials.
This is where Qnity™ Kalrez® O-rings deliver unmatched reliability.
The Challenge: Temperature + Chemicals + Pressure
Industrial sealing systems are exposed to:
- High temperatures up to 300–327°C
- Aggressive chemicals and steam
- High-pressure environments in valves and compressors
Standard elastomers fail due to cracking, swelling and high compression set leading to leakage and frequent maintenance.
Kalrez®: Built for Extreme Performance
- High Temperature Resistance
Kalrez® Spectrum™ 7075 operates up to 327°C, while grades like 7390 and 7375 perform reliably up to 300°C, even in steam environments. Ideal high temperature O rings up to 327°C for critical processes.
- Superior Chemical Resistance
Kalrez® shows low volume swell in acids, steam and reactive chemicals, ensuring long-term sealing performance. Perfect chemical resistant O rings and perfluoroelastomer seals in India.
- Low Compression Set = Reliable Sealing Under Pressure
- Kalrez® compounds offer very low compression set, even at high temperatures
- Maintains sealing force over time
Critical for high-pressure applications like valves, pipelines and mechanical seals
Key to preventing leakage and failures.
- Reduced Risk of Contamination
- Non-reactive material
- Maintains process purity. Essential for pharmaceutical and semiconductor environments
Applications in Oil & Gas
Kalrez® Spectrum™ 7390 is designed for demanding environments such as:
- Drilling and oilfield equipment
- Steam-assisted processes – Steam Assisted Gravity Drainage (SAGD), Cyclic Steam Stimulation (CSS)
- Valves, compressors and instrumentation
Ensures sealing reliability under steam, hydrocarbons, and pressure
