Semperit 4SP hydraulic hose 

The Semperit 4SP hydraulic hose is a high-strength four-layer hose designed according to the EN 856 4SP standard. It consists of: an inner rubber layer made of synthetic rubber resistant to hydraulic oils (mostly NBR – nitrile butadiene rubber), four spiral layers of high-strength steel wire – providing exceptional resistance to high working and pulsating pressures, and an outer rubber layer resistant to abrasion, weather conditions, and ozone. The hose is characterized by excellent durability, flexibility, and a high range of pressure resistance.

Purpose of four-braid hoses 

Semperit 4SP hoses are designed for high-pressure hydraulic systems, especially where high pulsating loads occur. They are used in, among others: construction machinery (excavators, loaders, cranes), industrial equipment, agriculture (tractors, presses), mining, and forestry. The operating temperature range usually spans from -40°C to +100°C, and up to +120°C when working with synthetic oils (depending on the specific model specifications).

This type of hose is used in hydraulic systems where very high pressures, large cyclic loads, and the risk of mechanical damage occur. They are ideal for construction machinery, hydraulic presses, forklifts, agricultural machinery, mining machinery, and industrial applications where reliability and strength are essential. The hose is suitable for working with hydraulic oils, water-oil emulsions, and other approved media described in the manufacturer's specification. Such hoses are indispensable in the following sectors: construction, agriculture, heavy industry, mining, transport, industrial production, the municipal sector, energy, and wherever heavy-duty, reliable power hydraulics are required.

DIN EN 856 4SP

What are din en 856 4sp hydraulic hoses ? They are lines designed for very high working pressures, used in power hydraulics in places where reliable operation under heavy loads is required. The 4SP version has four steel spiral braids that allow for the transfer of high pressures while maintaining flexibility and resistance to bending.

The Semperit DIN EN 856 4SP hydraulic hose is a multi-layer hydraulic line designed for high-pressure systems. Thanks to the use of four spiral braids made of high-strength steel and synthetic rubber resistant to aging and abrasion, the hose ensures stable operation even in the most demanding conditions. The construction was designed in accordance with the international EN 856 4SP standard, which guarantees durability, repeatability of parameters, and safety of use.

Characteristic features of SEMPERIT hoses 

These hoses are distinguished by a solid construction: an inner layer of synthetic rubber resistant to hydraulic oils such as HL, HLP, HLPD, HVLP, HFA, HFAS, HFB, and HFC ensures durability and compatibility with a wide range of media. Reinforcement in the form of four spiral layers of high-strength steel wire guarantees resistance to high working pressures, while the outer cover made of synthetic rubber protects against abrasion, ozone, and weather conditions. The cover material is MSHA approved, which means the line is also suitable for mining applications. The hose maintains its properties over a wide temperature range from -40°C to +100°C, and briefly even up to 120°C.
