The Carlock CP03-P is a high-performance, single-acting piston lip seal featuring an integrated O-Ring energizer in the groove. This unique design provides constant preload, ensuring an excellent sealing effect across all pressure ranges up to 400 bar.
Asymmetric single acting piston seal, with dynamic sealing lip being shorter than static one；
• O-ring in groove acts as energizer and creates preload；
• Interference fit on inside diameter；
• Various materials available for different purposes；
• Best sealing effect across wide temperature range；
• Sealing effect enhanced by high back-pumping ability；
• For pressure up to 400 bar as seal between pressurized space and atmosphere；
• Good sealing in all pressure ranges；
• Excellent static and dynamic sealing；
• Suitable for short stroke applications；
• No reverse leakage (i.e. minor relative motion of sealing edges when direction is changed)；
• Recommended when holding or positioning under pressure；
Leveraging our advanced CNC machining technology, Carlock offers 24-hour rapid delivery for both standard and oversized custom dimensions, with no mold fees required. The CP03-P is specifically engineered for applications requiring zero reverse leakage, making it the perfect functional alternative for high-pressure hydraulic cylinders, shifting functions (clutch), and clamping operations. Its asymmetric design, with the dynamic lip being shorter than the static one, eliminates drag pressure build-up, while specialized materials allow for reliable performance at temperatures as low as -50 °C.
