Four Steel Wire Spiral Hydraulic Hose DIN EN 856 4SP
DIN EN 856 4SP hydraulic hose is designed for high pressure applications to deliver petroleum-based hydraulic fluids. The hose consists of three parts: inner tube, steel wire winding reinforcement layer and outer rubber cover. The oil resistance of the inner rubber layer ensures the smooth delivery of hydraulic fluids. The reinforcement layer is wound with four layers of high-tensile steel wire, which gives it the strength and durability required to withstand high pressures up to 6000 psi. The outer rubber layer is an excellent synthetic rubber, corrosion and oil resistant, resistant to exposure to various environments, precipitation and UV radiation.
