The CR12-FS profile is a high-performance spring-energized axial seal specifically designed to prevent external pressure or media from entering between two faces. This specialized face seal excels in managing pressure gradients from outside to inside, handling operating pressures up to 350 bar (35 Mpa & 5,000 PSI) and maximum surges up to 700 bar (10,000 PSI). Engineered for extreme reliability, it operates across a wide temperature range from -260 °C to +315 °C (-436 °F to 600 °F), ensuring a secure barrier in vacuum services and aggressive chemical environments.

• External Gradient Sealing: Specifically engineered to prevent media ingress from the outside, ideal for vacuum and medium-pressure flange applications.
• High Compliance Design: Cantilever spring provides a low sealing load, accommodating flange vibrations and significant gaps between sealing areas.
• Agile Manufacturing: Utilizing No-Mold Required Seals and Precision-Machined Profiles to deliver custom-engineered solutions with zero tooling fees.
• Oversized Specialization: Large-scale CNC turning for non-standard hydraulic seals and precision-machined large seals up to 3000mm.
• Extreme Media Resistance: Characterized by extremely high temperature and chemical resistance, suitable for corrosive fluids services.
The CR12-FS features an advanced design with a cantilever spring, making it the preferred choice for flange sealing where only limited assembly forces are permissible. Its high compliance allows the seal to compensate for larger gaps and long-term flange separation caused by vibrations or thermal cycles. Specifically developed for PTFE materials, the CR12-FS offers exceptional chemical resistance and low friction during intermittent movements. Whether applied in cryogenic services or high-temperature machine tools, this external pressure face seal ensures uniform contact and long-term sealing integrity without stick-slip.
