10-20 mm Hydraulic Pipe Spiral Guard Custom Lengths Excellent Fatigue Resistance

Product Advantages Features

Hongruntong Marine’s 4SP high-pressure hydraulic hose is engineered for extreme durability in marine and offshore applications. Featuring four-layer high-tensile steel wire reinforcement, it delivers superior burst resistance (up to 85 MPa static pressure) while maintaining flexibility for easy routing in tight spaces. The oil-resistant synthetic rubber inner tube ensures long-term compatibility with mineral-based and biodegradable hydraulic fluids, while the abrasion- and UV-resistant outer cover withstands harsh saltwater environments.

Key Benefits

► Ultra-high pressure resistance – Ideal for shipboard hydraulic systems, winches, and heavy-duty offshore equipment.

► Superior corrosion resistance – Specially formulated rubber resists seawater, ozone, and chemical exposure.

► Long service life – Exceeds 500,000+ pulse cycles (ISO 6803 certified).
