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.
