4SP/4SH Hydraulic Hose Manufacturer

4SP Hydraulic Hose, 4sh, Hydraulic Hose

4SP/4SH                  Hydraulic Hose

This heavy-duty hydraulic hose is meticulously engineered for demanding applications involving petroleum-based hydraulic fluids. Designed to perform under extreme pressure and challenging working conditions, it is ideal for high-power hydraulic systems commonly found in construction, mining, and heavy machinery. The hose features an inner tube made from high-quality oil-resistant synthetic rubber, providing superior protection against fluid degradation and internal wear. This ensures consistent performance and extends the service life of the hose in various fluid-handling tasks. Reinforced with four spiral plies of high-tensile steel wire, arranged in alternating directions, the hose is built to endure high-pressure impulses while maintaining excellent flexibility and kink resistance. This robust construction allows the hose to handle working pressures up to 5,000 psi (345 bar), making it suitable for applications requiring high impulse resistance and durability.
