Fullständig produktbeskrivning

The NLG 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 outside to inside. It is the preferred choice for applications in which only limited assembly forces are permissible or which require compensation for larger gaps between sealing areas. It is also suitable for applications with minor movements caused by vibrations. The NLG series is characterized by extremely high temperature resistance and chemical resistance.

• Cantilever spring for low sealing load and high 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.
• Available with silicone filling for food and drug applications.

Range of application:
Flange sealing in medium-pressure applications, pressure gradient from outside to inside. Minor dynamics permissible.
