DIN EN 856 4SP/4SH 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.
The hydraulic hose DIN EN856 4SP/4SH is compatible with a variety of hydraulic oils and has a wide range of uses. It is suitable for various mechanical systems, such as mine hydraulic supports, oil field development equipment, engineering construction machinery, cranes, mining equipment, injection molding machinery, agricultural machinery and various machine tools, etc.
What is DIN EN 856 4SP/4SH?
4SP hydraulic hose is a high-performance hose that is reinforced with four layers of steel wire spirals. “4SP” refers to the structure of the hose, it is a 4-wire spiral hose. It has excellent flexibility and durability. The outstanding feature of the hose is that it can withstand extreme pressures, making it widely used in heavy-duty applications such as construction, agriculture, mining, and manufacturing industries. Not only that, 4SP steel spiral hydraulic hose is made of high-quality synthetic rubber and has excellent wear resistance, weather resistance, and oil resistance. For those users who are looking for reliability, durability, and high-pressure performance in hydraulic systems, 4SP hydraulic hose is a top solution.
What material is the EN856 made of?
EN856 refers to the German standard implementation standard, which is mainly used to specify the requirements of rubber-coated spiral wire reinforced hydraulic hoses and hose assemblies. These hoses include 4SP, 4SH, R12 and R13 types, suitable for different working conditions and media.
EN856 hydraulic hose is composed of an oil-resistant inner layer, a high-strength stainless steel wire winding reinforcement layer and a wear-resistant and weather-resistant outer layer.
What is the full form of 4SP/4SH?
4SP/4SH refers to DIN EN 856 4SP/4SH, a high-pressure hydraulic hose with four layers of steel wire spiral as reinforcement layer. Suitable for various high-pressure hydraulic systems to transport petroleum-based hydraulic fluids.
What is the difference between 4SP and 4SH hose?
DIN EN856 4SH and 4SP are both reinforced with four layers of steel wire winding. They are both suitable for high-pressure hydraulic systems. The main difference lies in the pressure bearing capacity and the outer diameter of the hose. The pressure of the 4SH hydraulic hose is slightly higher than that of the 4SP. At the same time, the outer diameter of the 4SH is slightly smaller than that of the 4SP, so the pressure that the 4SH can withstand is higher than that of the 4SP.
