CP02-P Heavy-Duty Asymmetric Piston Seal: 700 Bar High-Pressure Solution

•Asymmetric single acting piston lip seal, with dynamic sealing lip being shorter and thinner than static one in order to avoid drag pressure built up；

• Interference fit on inside diameter；

• Various materials available for different purposes；

• Best sealing effect across wide temperature range；

• Active back-up ring on low-pressure side of seal reduces extrusion and allows larger gap dimensions resp. higher system pressure；

• Sealing effect enhanced by high back-pumping ability；

• For pressure up to 700 bar as seal between pressurized space and atmosphere；

• Good sealing under low pressure；

• Excellent static and dynamic sealing；

• Suitable for long stroke applications；

• Little tendency to stick-slip；

• Low break-away force after prolonged periods of standstill；

• For shorter seal heights we recommend CP02-PD profile；

The Carlock CP02-P is a robust, single-acting asymmetric piston seal specifically engineered for heavy-duty applications where reliability is paramount. Designed to withstand extreme pressure peaks up to 700 bar, it serves as a high-performance functional equivalent for premium brand-name profiles used in mobile and stationary hydraulics.

Leveraging our advanced CNC machining technology, we provide 24-hour rapid delivery for all sizes, including oversized dimensions that are typically hard to source. The CP02-P features a dynamic sealing lip that is shorter and thinner than the static one to prevent drag pressure build-up, combined with an active back-up ring that minimizes extrusion. Whether you are maintaining heavy construction equipment or chemical process machinery, Carlock’s machined seals offer the perfect balance of extreme wear resistance and precision fit with no tooling costs
