The CR19-F profile is a premium single-acting rotary lip seal specifically developed for PTFE materials, featuring an integrated clamping flange to prevent seal rotation and stabilize the assembly against thermally induced movement. This spring-energized seal excels in high-pressure environments up to 200 bar (20 Mpa & 2900 PSI) and peripheral speeds reaching 10 m/s (32.8 ft/s). Engineered for versatility, it operates across an extreme temperature range from -260 °C to +315 °C (-436 °F to +600 °F), ensuring a tight seal for rotating shafts in pumps, motors, and rotary actuators.

• Anti-Rotation Stability: Integrated outside flange clamps into the groove, preventing seal movement and resisting high-speed mechanical torsion.
• Extreme Media Resilience: Optimized PTFE jacket is compatible with aggressive chemicals, steam sterilization, and high-pressure NACE oil field services.
• Precision Customization: Produced via High-Precision Lathe-Cut techniques to provide Bespoke Sealing Solutions tailored to specific industrial housings.
• Heavy-Duty Performance: Heavy-duty hydraulic seals for oversized cylinders and robust sealing solutions for 3000mm large-bore hydraulics.
• HI-Clean Compatibility: Available with silicone-filled cavities to eliminate dead space, ideal for the pharmaceutical and foodstuff industries.
The CR19-F features a heavy dynamic inside lip and a cantilever spring for low-load, high-compliance behavior, making it the best choice for sealing viscous media, mud, or adhesives. Its flanged heel ensures the seal remains tight in the groove even during oscillating or helical movements, effectively protecting against mechanical torsion. For high-purity applications. Whether used in injection molding machines, pivoting motors, or the chemical industry, this profile offers high abrasion resistance, excellent aging properties, and a superior scraping effect.
