Custom Cap Seals (CCS)

The Chesterton CCS is a custom-engineered cap seal designed to meet specific application demands where off-the-shelf solutions fall short. Ideal for oversized, hard-to-find, or performance-critical hydraulic and pneumatic cylinders, these seals are individually sized and molded to fit each unique groove and operating condition.

Available with a range of engineered polymer materials—such as PTFE blends and urethanes—the CCS delivers superior sealing performance under high pressure and tough duty cycles. Custom gland profiles ensure precise fit and reliable operation, which helps minimize leaks, reduce downtime, and extend component life. This flexible approach delivers tailored sealing solutions for challenging applications in industries like heavy equipment, energy, manufacturing, and water treatment.
