4 Inch HDPE Hose Floats High Floating Design Low Water Absorption Saltwater Compatible
Hongruntong Marine's Heavy-Duty Hose Floats are engineered for demanding offshore and marine environments. Made from UV-resistant, high-buoyancy polyethylene, these floats ensure optimal hose positioning while preventing tangling and abrasion. Their corrosion-proof, saltwater-compatible design guarantees long-term durability, even in harsh conditions. With quick-release buckles and adjustable straps, installation is effortless, reducing downtime. Ideal for firefighting, dredging, and oil transfer operations, our floats enhance safety and efficiency on any vessel or platform.

*NOTE: Custom floaters are available.
Our floats incorporate advanced UV inhibitors that provide 2,000+ hours of accelerated weathering resistance (ASTM G154 tested), ensuring no degradation or color fading in prolonged sunlight exposure - critical for offshore operations.
Engineered with closed-cell polyethylene foam (4.5lb/ft³ density) that delivers 22% greater buoyancy per unit volume compared to standard EVA foam, while maintaining exceptional compression resistance.
Feature triple-layer protection: (1) anti-corrosive polymer shell, (2) zinc-plated stainless steel hardware, and (3) sacrificial anode ports - achieving 500-hour salt spray test compliance (ASTM B117).
Rib-reinforced structure withstands 50J direct impacts (ASTM D256) without cracking - 3X more durable than conventional float designs for heavy construction or mining applications.
- Offshore oil rig hose support
- Ship-to-shore fuel transfer
- Dredging operations
- Floating pipeline systems
- Marine salvage operations
