Hydraulic hose DN20 2SN 3/4" 215 bar smooth – two steel braids

The DN20 2SN 3/4" 215 bar hydraulic hose is a high-pressure rubber line with a smooth outer surface, designed for work in power hydraulic systems. The hose construction utilizes two steel wire braids, providing reinforcement during the transport of oil under pressure. The maximum working pressure is 215 bar, and the minimum burst pressure is 860 bar. The line has a nominal diameter of DN20, corresponding to the 3/4" size, and a minimum bending radius of 240 mm. The smooth, black outer cover is resistant to abrasion, oils, weather conditions, and ozone. The hose is used for creating flexible hydraulic connections in industrial machinery and equipment.

Application and technical characteristics

The DN20 2SN smooth hydraulic hose is primarily intended for transferring hydraulic oil in agricultural, construction, and industrial machinery installations. It can be used in pressure circuits and other connections requiring a flexible hose, provided the system's operating parameters are consistent with the hose's properties. When selecting, pressure, temperature, type of medium, and installation conditions should be taken into account.

The DN20 designation corresponds to the nominal size of 3/4". According to the technical table, the internal diameter of the line ranges from 18.6 to 19.8 mm. Proper diameter selection is important for oil flow velocity and pressure losses. The required efficiency of the hydraulic system and the length of the finished assembly should also be considered.

The 2SN construction includes two steel braids providing pressure reinforcement. The allowable working pressure is 215 bar, while the minimum burst pressure is 860 bar. Burst pressure is a strength parameter and does not mean the allowable operating pressure. Commercial documentation indicates construction compliance with EN 853 2SN and SAE J517 100R2AT.

The internal layer of the hose is made of black synthetic rubber-based compound, resistant to oil and water. Two steel braids are surrounded by an external rubber layer with a smooth surface, protecting the construction against abrasion, oils, ozone, and the effects of weather conditions. The NBR material is also indicated in the product specification.

The standard operating temperature range is from -40°C to +100°C. The line is intended for appropriate hydraulic fluids compliant with ISO 6743-4, excluding groups HFD R, HFD S, and HFD T. The commercial documentation also permits selected aqueous solutions at temperatures from -40°C to +70°C, water from 0°C to +70°C, and compressed air from 0°C to +80°C. The hose is not intended for transporting liquids containing castor oil and esters.

Smooth outer surface and end crimping

A distinguishing feature of the offered hose is the smooth outer surface. When designing the hose path, its outer diameter and the minimum bending radius of 240 mm must be taken into account. Excessive bending, twisting, and rubbing against sharp edges can lead to hose damage. In places exposed to intense friction, it is worth using appropriate mechanical protection.

The DN20 2SN hose can be used for making finished hydraulic assemblies with crimped ends. The assembly process requires the selection of compatible ferrule sleeves and fittings, as well as the correct crimping diameter. Crimping parameters provided for the specific set of components should be used. The maximum working pressure of the finished assembly is determined by the component with the lowest allowable pressure.

Why choose the DN20 2SN smooth hydraulic hose?

Smooth, black outer surface distinguishing the line from the textured surface version.
Working pressure of 215 bar and minimum burst pressure of 860 bar.
DN20 nominal diameter corresponding to the 3/4" size.
Construction reinforcement with two steel braids.
Minimum bending radius of 240 mm.
Standard operating temperature range from -40°C to +100°C.
Outer rubber layer resistant to abrasion, oils, weather conditions, and ozone.
Possibility of making a complete hydraulic assembly with appropriately selected ends.

Frequently Asked Questions (FAQ)

What pressure does the DN20 2SN smooth hydraulic hose withstand?

The hose is designed to work at pressures up to 215 bar. The minimum burst pressure is 860 bar, but it is not the allowable operating pressure for the hose.

What is the actual inner diameter of the DN20 3/4" hose?

According to the technical table, the inner diameter is between 18.6 and 19.8 mm. The DN20 designation is a nominal size, corresponding in this case to the 3/4" size.

What is the minimum bending radius of the DN20 2SN smooth hose?

The minimum bending radius is 240 mm. This value should be observed when routing the hose to avoid excessive stress and damage to its construction.

Is the smooth DN20 2SN hose suitable for crimping?

Yes. The hose can be used for producing a complete hydraulic assembly with crimped ends. Compatible ends and ferrule sleeves must be selected, and correct crimping parameters must be applied.

How does the smooth version differ from the PREMIUM DN20 2SN hose?

The smooth version has an outer surface without a distinct texture and different dimensional parameters. Its minimum bending radius is 240 mm, maximum outer diameter is 30.1 mm, and unit weight is 1.01 kg/m. The selection of a specific variant should consider the installation requirements and technical parameters of the entire system.
