4 Inch Hose Floats High Floating Design Low Water Absorption Saltwater Compatible
Introduction
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.

Key Features
Marine Grade UV Stabilization
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.
High Density Buoyancy Core
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.
Saltwater Corrosion Protection
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).
Industrial Grade Impact Resistance
Rib-reinforced structure withstands 50J direct impacts (ASTM D256) without cracking - 3X more durable than conventional float designs for heavy construction or mining applications.
Applications
► Offshore oil rig hose support
► Ship-to-shore fuel transfer
► Dredging operations
► Floating pipeline systems
► Marine salvage operations
