Marine Pneumatic Cylinders for Offshore & Saltwater Environments

Corrosion-Resistant Marine & Offshore Pneumatic Cylinders

American Cylinder designs, develops and delivers high-quality, long-lasting marine pneumatic cylinders for use in marine and offshore environments. Our non-repairable corrosion-resistant (CR) air cylinders and stainless steel cylinders are expertly engineered to withstand the elements typically found in lakes, rivers, and oceans - moisture, lubricants, and solvents. As a leading provider of marine and offshore pneumatic cylinders, our team of experts can assist you with all your needs. Every cylinder is built to ISO 9001:2015 standards and pre-tested before it ships, so you can specify with confidence for demanding marine automation, deck equipment, and shipboard control applications.

Marine-Grade Air Cylinders

American Cylinder manufactures corrosion-resistant air cylinders and stainless steel non-repairable cylinders for marine use. Our products offer an impressive array of features and benefits, making them ideal for demanding marine applications. Whether you need a single cylinder for a control panel actuator or a full production run for OEM shipboard equipment, our marine-grade cylinders are engineered to perform in humid, saltwater, and washdown-prone environments.

Frequently Asked Questions About Marine Cylinders

What makes a pneumatic cylinder suitable for marine environments?

Marine-suitable pneumatic cylinders need corrosion resistance to withstand saltwater, moisture, and washdown chemicals. American Cylinder’s CR and stainless steel cylinders use Type 304/303 stainless steel and acetal components, engineered specifically to resist the corrosive elements found in lakes, rivers, and ocean environments.

Are American Cylinder’s marine cylinders corrosion-resistant?

Yes. American Cylinder’s CR Series and stainless steel non-repairable cylinders are built with Type 304 stainless steel bodies and Type 303 stainless steel rods, specifically engineered to resist moisture, lubricants, and solvents common in marine and offshore settings.

What bore sizes are available for marine pneumatic cylinders?

American Cylinder’s marine-grade cylinders are available in bore sizes ranging from 5/16" to 3", in single-acting, double-acting, and volume chamber configurations, giving engineers flexibility to match force and space requirements for shipboard and offshore equipment.

Can American Cylinder build custom cylinders for offshore applications?

Yes. American Cylinder’s engineering team designs custom pneumatic cylinders for unique offshore requirements, including non-standard rod extensions, special seal compounds, and oversized ports, all backed by ISO 9001:2015-certified manufacturing processes.

What certifications does American Cylinder hold for its marine cylinders?

American Cylinder is ISO 9001:2015 certified. Every marine pneumatic cylinder is pre-tested to confirm zero leakage before shipment and pre-lubricated with a high-endurance or FDA-approved oil mixture, depending on application requirements.
