The NLA product series is a FlexiSeal® design with a cantilever spring. It is ideally suited for static applications requiring greater flexibility of the seal cross-section (spring travel) due to higher coaxiality fluctuations between the rod and groove or due to excessive expansion and contraction (“breathing”). It is characterized by extremely high temperature and chemical resistance. NLA may also be used for dynamic applications (internal and external).

• Symmetric lip design.
• Cantilever spring for low load / high compliance behaviour.
• 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.
• Allows the integration of a stand-off ring to protect the sealing lips in case of reverse pressure.
