The Yokohama Pneumatic Fender (also known as Marine Air Bag Dock Fender) is a high-performance marine protection solution developed by China Marine Rubber (Qingdao) Industrial Co., Ltd., a professional manufacturer focusing on Rubber Fender System. This fender uses internal compressed air as the cushioning medium to effectively absorb impact energy, making it suitable for both small and large vessels. Available in a wide range of sizes (from 300×500mm to 4500×9000mm), it provides reliable protection for hulls and docks during berthing or ship-to-ship operations. Smaller models are designed with hook-type installations for easy handling, while larger fenders are equipped with chain-type nets to enhance structural protection.

Inspect the Yokohama Pneumatic Fender for surface damage or air leaks before installation.
For small hook-type fenders: Fix the hooks to the vessel’s designated mounting points, ensuring a secure connection.
For large chain-net fenders: Wrap the chain net around the fender first, then attach the net to the dock or vessel using steel cables.
Inflate the fender to the specified test pressure (8–175 Kpa, depending on size) using a pressure-regulated air pump.
Check the internal pressure weekly; refill air if pressure drops below the recommended level.
Inspect the rubber surface and chain net monthly for wear, cracks, or rust; replace damaged parts promptly.
Clean the fender with fresh water regularly to remove salt deposits and marine organisms.
The Yokohama Pneumatic Fender complies with international marine standards, including:
ISO 9001 Quality Management System Certification
CCS (China Classification Society) Certification
Strict quality control during production, from raw rubber selection to final product testing, ensuring consistent performance.
China Marine Rubber provides a 12-month warranty for manufacturing defects, with professional after-sales support.
Yes. We offer customized sizes (beyond the standard range) and accessories (e.g., special chain nets) to meet specific customer needs. Contact our sales team for details.
Stop using the fender immediately, deflate it, and inspect the leak location. Small leaks can be repaired with rubber repair kits; large leaks require professional maintenance or replacement.
