Import Flex 4sh/ 4sp — Buy in Bulk from Supplier in China

Flex 4SH/4SP is a high-pressure hydraulic hose designed to EN 856 standards, featuring a four-wire braid reinforcement and a synthetic rubber cover resistant to oil and weathering. The inner tube is formulated for compatibility with hydraulic fluids such as HFD-U, HFC, and mineral oils. This hose is rated for working pressures up to 345 bar and operates within a temperature range of -40°C to +100°C, making it suitable for heavy-duty industrial and mobile equipment applications.

The construction follows the EN 856 4SP/4SH specification, with an inner tube of nitrile rubber, four layers of spiral steel wire reinforcement, and a cover of chloroprene or EPDM rubber. Typical industry variants include different cover types for abrasion resistance or UV exposure, and standard sizes range from 6.35 mm to 38.1 mm inner diameter. The hose is not reinforced with textile layers, distinguishing it from lower-pressure 1SN or 2SN types. Material composition aligns with ISO 6802 and SAE J517 standards for hydraulic hose performance.

This hose is commonly used in construction machinery, agricultural equipment, mining vehicles, and marine hydraulic systems. Buyers include OEM manufacturers, industrial maintenance suppliers, and equipment distributors across Europe, Southeast Asia, and the Middle East. Trade terms are typically FOB Qingdao or CIF, with minimum order quantities starting at 100 meters per size. Packaging is on wooden reels or in bulk coils, with each meter marked with batch code and pressure rating.
