1.2m Marine Rubber Airbags Compact Lightweight High Pressure Tolerance

1.2m Marine Rubber Airbags Compact Lightweight High Pressure Tolerance


Description


Replace traditional ship launching methods with our eco-friendly Marine Airbags, reducing environmental impact without compromising performance. Made from high-grade rubber with low maintenance requirements, they eliminate the need for grease, heavy machinery, or permanent slipways. Their shock-absorbing design protects vessels during launch, while their reusability makes them a sustainable choice. Ideal for shipyards looking to cut costs and reduce carbon footprints. Available in multiple sizes (1m–4m) with high pressure tolerance for secure operations.
