Hydraulic hose 4SP DN20 (3/4") Premium 350 bar - 20m roll

The 4SP DN20 (3/4") hydraulic hose in the Premium version is a high-pressure technical hose designed for use in the most demanding power hydraulic systems. The construction based on four tightly wound high-strength steel wire spirals ensures stable operation under a constant working pressure of 350 bar, effectively eliminating the risk of damage during sudden impulse loads and pressure spikes. It is a professional-grade solution, forming the foundation of safe installations in machines with high work dynamics.

The inner layer of the hose is made of synthetic rubber (NBR), which exhibits full resistance to hydraulic oils and fuels. The outer cover, characterized by increased resistance to abrasion, ozone, and atmospheric conditions, guarantees a long hose life in difficult field environments. Due to the spiral reinforcement construction, assembly requires precise end preparation. For correct hose crimping, appropriately selected ferrules for 4SP and 4SH hosesare necessary to ensure installation tightness. In the process of building complete hose assemblies, we also recommend our professional hydraulic fittings. If you need servicing or wish to make hose assemblies yourself, we offer a service such as hydraulic hose crimping, which allows for maintaining the highest technical safety standards.

Application

The Premium 4SP DN20 hose is dedicated to supplying systems in advanced machinery and equipment:

Heavy construction equipment: excavators, loaders, cranes, and crushers requiring hoses with high resistance to material fatigue.
Forestry machinery: harvesters and forwarders operating in demanding environments.
Heavy industry: stationary production lines, hydraulic presses, and installations requiring constant high performance.

Operational benefits

High working pressure of 350 bar guarantees operational safety in high-load systems.
The use of four steel spirals minimizes the risk of failures resulting from pressure pulsations.
An excellent strength-to-flexibility ratio makes it easy to route the hose in tight machine spaces.
High resistance of the outer layer to ozone and atmospheric conditions.

FAQ – Questions and answers

Does the 4SP DN20 hose require skiving during crimping?
Yes, due to the spiral reinforcement construction, it is necessary to remove the outer rubber layer at the ferrule crimping point. This allows for direct contact between the ferrule and the wire, ensuring the durability and safety of the connection.

Can this type of hose be used in forestry machinery?
Definitely yes. Thanks to the use of an abrasion-resistant outer layer, this hose shows high durability in environments where hoses are exposed to contact with external elements.

What is the minimum bend radius for this hose?
For size DN20 (3/4"), the bend radius is 280 mm. Remember not to exceed this value, as too tight a bend can lead to material fatigue and shortened service life.
