Caterpillar Piston Seals are double-acting hydraulic piston seals with a nylon sealing face and rubber energizer, designed to provide reliable leak-resistant sealing, pass efficiently over ports, maintain pressure, and support heavy machinery performance in demanding applications.
Caterpillar Piston Seals are designed for hydraulic cylinder piston applications requiring reliable sealing and pressure retention. As double-acting seals, they support sealing performance in both directions and are engineered to pass efficiently over ports, helping maintain smooth cylinder operation in heavy machinery hydraulic systems.
These piston seals feature a nylon sealing face with a step-cut joint for easier installation, combined with a rubber energizer for improved sealing function. Their durable structure helps reduce leakage, maintain system efficiency, lower downtime, and extend equipment service life in harsh working environments.

With flexible 1-piece MOQ, fast 5–7 day delivery for small orders, and stable weekly supply capacity, we help repair shops, distributors, and equipment owners replace worn piston seals quickly, improve sealing reliability, and keep heavy machinery operating efficiently.
