The CR18-F profile is a high-load helical spring-energized axial seal specifically engineered to prevent external pressure or corrosive media from entering between two faces. Designed for high-pressure flange applications, this face seal excels in managing pressure gradients from outside to inside, handling operating pressures up to 550 bar (55 Mpa & 8000 PSI) and maximum surges up to 700 bar (10,000 PSI). Its helical wound spring provides a constant high load and a gas-tight seal even under fluctuating temperature cycles from -260 °C to +315 °C (-436 °F to +600 °F).

• Gas-Tight Integrity: Helical wound spring provides high seating load for reliable sealing of gases, vacuums, and aggressive chemicals.
• Extreme Gradient Resistance: Specifically engineered for external pressure gradients, maintaining performance up to 550 bar and maximum safety peaks.
• Precision Manufacturing: Produced via High-Precision Lathe-Cut techniques to provide Tailor-made Hydraulic Seals for critical OEM equipment.
• Robust Heavy-Duty Design: Robust sealing solutions for 3000mm large-bore hydraulics and high-performance large seals for extreme machinery.
• Cryogenic & FDA Service: Compatible with temperatures as low as -260°C and suitable for both contact and non-contact FDA regulated media.
The CR18-F features a specialized FlexiSeal® design with a helical spring, making it the ideal choice for static flange sealing where a small deflection range and high contact force are required. Its superior material compatibility allows for use in vacuum service, aggressive chemicals, chlorine, and NACE-regulated oil field applications. The seal's robust construction ensures it remains gas-tight under intermittent movement or vibration. Whether applied in cryogenic services or high-temperature fugitive emission control, the CR17-F provides an exceptional barrier against gases and liquids, even in dry-running conditions across a wide range of gases.
