Inflatable Boat Accessories Natural Rubber Pneumatic Fender Durable Marine Boat Use ISO Certified 0.5-4.5m Hot Sale

Pneumatic rubber fender, also known as Yokohama fender, is manufactured using rubber and multiple layers of rubber-dipped tire fabric. It serves as a leading anti-collision device for marine applications worldwide.

Floating pneumatic rubber fenders are constructed from synthetic-cord-reinforced rubber sheets with compressed air inside. The internal air enables flotation on water and functions as a shock absorber between ships (ship-to-ship) or between ships and berthing structures during docking operations.

• Reinforced synthetic-tire-cord layers providing strong stability, heat resistance, fatigue resistance, and impact load resistance
• No mold vulcanization with advanced surrounding molding process
• Single-formed rubber capsule wall eliminating secondary joints and improving overall strength
• Thin, soft walls with excellent contact deformation performance and high energy absorption
• Superior adaptability to inclined contact up to 15 degrees
• Floating design accommodating multi-directional ship docking
• Easy installation and handling

Ships typically make initial contact with docks or other vessels at oblique angles during STS operations. Unlike solid rubber or foam fenders, which experience reduced performance at inclined compression, inflatable rubber fenders maintain consistent energy absorption even at compression angles up to 15 degrees.

Zhonghaihang Pneumatic Rubber Fenders consist of three primary components vulcanized into a firm structure:

• Outer Rubber: Protects cord layers and inner rubber from abrasion and external forces with sufficient tensile and tear resistance
• Reinforcement Synthetic-Tyre-Cord Layer: Maintains internal air pressure with strong stability
• Inner Rubber Layer: Seals pressurized air inside the fender

Fenders with diameters of 2500mm and larger include safety valves to release excess internal pressure during accidental over-compression. The assembly features metal end components with dual flanges and bolt/nut clamping, similar to automotive tire valve structures.

• Maintain fender pressure within standard air pressure ±5% range
• Check air pressure every three months and adjust as needed
• Avoid contact with sharp objects
• When not in use for extended periods: wash, dry, fill with proper compressed air, and store in cool, dry, ventilated areas
• Store away from heat sources, acids, alkalis, oils, and greases
• Do not fold or stack during storage
