The Carlock CP03-S is a premium single-acting piston seal featuring an integrated Helicoil spring for consistent and high contact pressure even at low compression. Designed for extreme reliability, this profile offers exceptional static and dynamic sealing across a wide temperature range, making it ideal for both reciprocating and swivelling applications.
Asymmetric single acting piston seal, with dynamic sealing lip being differently shaped than static one；
• Preload is created by helicoil spring inserted in groove；
• Interference fit on inside diameter；
• One sealing edge for profile widths smaller than 5 mm; three sealing edges for widths of 5 mm or more；
• Various materials available for different purposes；
• Good sealing effect across wide temperature range；
• Sealing effect enhanced by high back-pumping ability；
• For pressure up to 200 bar as seal between pressurized space and atmosphere (in certain cases also above that, see seal data sheet)；
• Good sealing in all pressure ranges；
• Good static and dynamic sealing after short run-in time；
• Suitable for short and long stroke applications；
• No reverse leakage (i.e. minor relative motion of sealing edges when direction is changed)；
• Little friction when dry-running or when used in media with poor lubrication (limited usage in aqueous media)；
• Low break-away force；
• High contact pressure at low spring compression；
Leveraging our advanced CNC machining technology, Carlock provides 24-hour rapid delivery on both standard and oversized custom dimensions, serving as a high-end functional alternative for international brands. The CP03-S excels in dry-running conditions or media with poor lubrication, offering significantly low break-away force and minimal friction. With zero reverse leakage and a robust design featuring up to three sealing edges for larger widths, it is the perfect solution for push rods, chemical industry fittings, and high-performance cylinders.
