Composite Hose
Ideal for marine loading/unloading, tanker-to-shore transfer, rail car and truck loading, bunkering, and chemical processing, the composite hose combines lightweight construction (up to 40% lighter than traditional rubber hoses), outstanding chemical compatibility, and superior flexibility, making it the preferred choice for safe and efficient fluid transfer operations.
