Product Overview
High-Performance Air Cylinder Rubber Gaskets are precision-engineered sealing components designed to ensure leak-free operation in pneumatic actuators and cylinders. Manufactured from premium elastomers including NBR, Polyurethane, FKM, and Silicone, these gaskets provide exceptional durability, minimal friction, and reliable performance across millions of cycles.
Ideal for industrial automation, manufacturing equipment, and mobile machinery, our air cylinder gaskets are engineered to withstand high-pressure environments, temperature fluctuations, and both lubricated and dry-run conditions.
Structure & Cross-Section
 |
Precision-Molded Piston & Rod SealsOur air cylinder gaskets feature optimized cross-sectional profiles designed for maximum sealing efficiency with minimal friction. The precision-molded lip geometry ensures consistent contact pressure across the sealing surface, preventing air leakage while allowing smooth piston movement. Available in various profiles including U-Cup, V-Ring, and O-Ring configurations, each design is tailored to specific cylinder bore sizes, stroke lengths, and operating pressures. Commonly used in double-acting cylinders, single-acting actuators, and rodless pneumatic systems. |

FAQ – Request For Quotation
❓ What information should I provide for a quotation?
Please provide the cylinder bore diameter, rod diameter, gasket profile type (U-Cup, V-Ring, O-Ring), material preference, and operating pressure. Technical drawings or samples greatly speed up quotation accuracy.
❓ Can you manufacture gaskets for non-standard cylinder sizes?
Yes, we specialize in custom molding. Provide your cylinder specifications and we can design and produce gaskets to exact dimensions with appropriate tooling.
❓ What is the minimum order quantity (MOQ)?
For standard sizes, there is no MOQ. For custom tooling, we typically require a minimum order to justify mold development costs, which we can discuss individually.
❓ How do I choose between NBR and Polyurethane?
NBR is ideal for lubricated systems and offers excellent oil resistance at a lower cost. Polyurethane excels in dry-run applications and high-pressure environments due to superior abrasion resistance.
❓ What are the lead times for production and delivery?
Stock gaskets ship in 2-3 days. Custom sizes with new tooling typically take 15-25 working days depending on complexity. Expedited production is available for urgent projects.
