Hydraulic hose DN08 2SC SUPER 2K 425 bar smooth

The DN08 2SC SUPER 2K hydraulic hose is a compact high-pressure hose with a smooth outer surface, designed for use in power hydraulic systems. The DN08 nominal diameter corresponds to the 5/16" size, and the maximum working pressure is 425 bar. The hose construction uses two high-strength steel wire braids, providing reinforcement during pressurized operation. An oil-resistant inner layer allows for the transport of suitable hydraulic fluids, while the smooth outer cover protects the hose from abrasion, oils, and weather conditions. The operating temperature range from -50°C to +100°C also allows the hose to be used in low-temperature installations.

Application and technical characteristics

The SUPER 2K DN08 2SC hose is designed for flexible hydraulic connections in industrial, agricultural, and construction machinery and equipment. It is used in systems requiring compact hoses with high working pressure. When selecting, the required pressure, flow rate, medium temperature, and installation mounting conditions should be considered.

The DN08 nominal diameter corresponds to the 5/16" inch size and an internal diameter of approximately 8 mm. Proper selection of the hose diameter has a direct impact on oil flow speed and pressure losses. When designing an installation, pump efficiency, hose length, and the requirements of hydraulic receivers should be taken into account.

The 2SC construction is characterized by a compact design and the use of two reinforcing steel braids. The SUPER 2K DN08 hose is suitable for a working pressure of 425 bar, allowing it to be used in appropriately selected high-pressure systems. Compared to standard double-braid hoses, the compact design makes it easier to design connections in areas with limited installation space. However, when selecting, actual external dimensions and the minimum bending radius should always be taken into account.

Hose construction and material resistance

The inner layer of the hose is made of special synthetic rubber resistant to mineral, vegetable, and hydraulic oils. The reinforcement consists of two high-strength steel wire braids. The outer cover made of synthetic rubber has a smooth surface and is resistant to abrasion, oils, and weather conditions. NBR material was used in the construction of the hose, and the color of the external surface is black.

The hose can operate at temperatures from -50°C to +100°C, with an allowable periodic temperature increase to +125°C. Elevated periodic temperature does not mean the possibility of continuous operation under such conditions. Permissible usage conditions should always be assessed taking into account the type of medium, working pressure, and characteristics of the entire installation.

Technical standards of the DN08 2SC SUPER 2K hose

The SUPER 2K hose belongs to the group of compact 2SC hydraulic hoses, for which the requirements of EN 857 2SC and ISO 11237-1 2SC standards are applied. Technical designations of the hose also include TS EN 857 TYPE 2SC, ČSN EN 1804-3, ISO 1307, and ISO 6805. Individual standards refer to specific construction, dimensional requirements, or hose testing methods. For applications requiring specific normative compliance, the appropriate range of technical requirements should be considered.

The working pressure of 425 bar is a parameter of the specific SUPER 2K DN08 variant. The 2SC construction designation does not mean that all hoses of this type have identical working pressure. Individual variants may also differ in outer diameter, bending radius, and requirements for fitting assembly.

2SC hydraulic hose replacement – 2SNK hose

An alternative to compact 2SC hydraulic hoses can be 2SNK type hoses. The HYDRON offer also includes PREMIUM DN08 2SNK 420 bar hydraulic hose, which can be considered when selecting a replacement hose for a hydraulic system.

The SUPER 2K DN08 2SC hose has a working pressure of 425 bar, while the PREMIUM DN08 2SNK hose is designed for 420 bar. Using an alternative hose therefore requires checking the maximum pressure occurring in the installation and other technical parameters. Particularly important are the hose diameter, minimum bending radius, external dimensions, and compatibility of fittings and crimping ferrules. The 2SNK hose should only be used when its parameters match the requirements of the specific system.

Crimping fittings and preparing hydraulic hoses

The DN08 2SC SUPER 2K hydraulic hose is intended for making complete hydraulic assemblies with crimped fittings. For assembly, compatible fittings and crimping ferrules, appropriately selected for the compact 2SC construction, should be used. It is important to properly prepare the hose end and maintain the correct crimping diameter for the set of components used.

Crimping parameters intended for standard 2SN hoses or 2SNK hoses should not be applied automatically. Structural and dimensional differences may require the use of different ferrules and press settings. The permissible working pressure of the finished hydraulic assembly is determined by the component with the lowest pressure rating.

During hose installation, avoid twisting the hose around its axis, excessive bending, and contact with sharp edges. Proper routing of the hose and the use of appropriate mechanical protection helps reduce the risk of damage to the outer cover and the steel reinforcement.

Frequently Asked Questions (FAQ)

What is the working pressure of the SUPER 2K DN08 2SC hose?

The DN08 2SC SUPER 2K hose is suitable for a maximum working pressure of 425 bar. The pressure of a complete hydraulic assembly also depends on the parameters of the fittings used and other connection elements.

Can the DN08 2SC hose be replaced by a 2SNK hose?

In specific applications, it is possible to use a 2SNK hose as an alternative to a compact 2SC hose. This requires comparing the working pressure, diameters, minimum bending radius, and compatibility of the crimped elements. The PREMIUM DN08 2SNK 420 bar hose has a lower working pressure than the SUPER 2K 425 bar model, so it cannot be treated as an unconditional replacement.

Which technical standards apply to the DN08 SUPER 2K hose?

The technical markings include EN 857 2SC, ISO 11237-1 2SC, TS EN 857 2SC, ČSN EN 1804-3, ISO 1307, and ISO 6805. Individual standards apply to various technical requirements and methods for testing hydraulic hoses.

Is the SUPER 2K DN08 hose suitable for low-temperature operation?

Yes. The lower operating temperature is -50°C, and the upper continuous operating temperature is +100°C. The allowable periodic temperature is +125°C. The application of the hose should be adapted to the properties of the medium and the parameters of the entire installation.

Can hydraulic fittings be crimped onto the DN08 2SC hose?

Yes. The hose is intended for making assemblies with crimped hydraulic fittings. For assembly, compatible fittings and ferrules should be selected, and the correct crimping parameters for the 2SC construction should be applied.
