The CR12-F profile is a high-performance single-acting axial lip seal specifically developed for PTFE materials and cantilever spring reinforcement, designed to prevent internal pressure or media from exiting between two faces. This spring-energized seal excels in static applications up to 700 bar (70 Mpa & 10,000 PSI) and dynamic scenarios up to 350 bar (35 Mpa & 5,000 PSI). Engineered for extreme environments, it maintains a reliable seal across a vast temperature range from -200 °C to +260 °C (-328 °F to 500 °F), making it the preferred choice for cryogenic and high-heat services.

• Extreme Environment Reliability: Performs in temperatures ranging from cryogenic -200°C to 260°C, ideal for NACE and chlorine services.
• Low Load Sealing: Cantilever spring design allows for high compliance and effective sealing even with limited assembly forces or flange vibration.
• Agile Manufacturing: Utilizing Custom-Engineered Profiles and Rapid Prototyping to meet urgent industrial requirements without tooling delays.
• Robust Industrial Design: Robust sealing solutions for 3000mm large-bore hydraulics and high-performance large seals for extreme heavy machinery.
• FDA & Chemical Compliance: Highly resistant to aggressive chemicals and suitable for both contact and non-contact FDA applications.
The CR12-F features a design with a large spring travel cantilever spring, ensuring low sealing loads and high compliance to long-term flange separation. Its PTFE construction provides wide media compatibility, covering vacuum service, aggressive chemicals, NACE, and FDA-regulated environments. The seal's flexible lip compensates for large gaps and vibrations, offering no stick-slip and low breakaway torque even after standstill. Whether used as a static seal for lids or a dynamic axial seal in valves and armatures, the CR12-F provides exceptional wear resistance and dry-running capability in gaseous or aqueous media.
