Flange seal. Internal pressure. Static and intermittently dynamic. FlexiSeal. Spring-energized PTFE seal. Low assembly force.
The NRI product series features a FlexiSeal® design with a cantilever spring and is ideally suited for flange sealing in medium-pressure applications. It seals the pressure gradient from inside to outside. The NRI series is characterized by extremely high temperature resistance and chemical resistance.
• Wiper-type lips.
• Cantilever spring with high-load/high-compliance to resist permanent set and long-term flange separation.
• Rigid spring acts as a control band to resist low-temperature shrinkage.
• Available in large cross sections, ideal for large-diameter seals.
• NACE-approved energizers available for oil field use.
Range of application:
Flange sealing in medium-pressure applications, pressure gradient from inside to outside. Cryogenic applications.
