Item Information

The NHE product series features a FlexiSeal® design with a helicoil spring and is ideally suited for flange sealing in extreme high-pressure applications. It seals the pressure gradient from outside to inside. The NHE series is characterized by extremely high temperature resistance and chemical resistance.

• Extended heel reduces the effects of extrusion.
• Helical spring for high load and small deflection range.
• Resilient helical spring resists permanent set and maintains compliance to long-term flange separation.
• Many high-resilience energizer options available, including choice of light, medium and heavy loads and NACE for oil field use.
• Low-cost elastomeric energizers available, all with excellent fatigue resistance.

Range of application:
Flange sealing in extreme high-pressure applications, pressure gradient from outside to inside.
