Thermoplastic hose R8 DN06 350 bar with two aramid braids

The R8 DN06 thermoplastic hose is a high-pressure hydraulic line with an internal diameter of 6 mm (1/4"), designed for conveying mineral and synthetic hydraulic oils, as well as appropriately selected water-based fluids. The reinforcement consists of two braids of high-strength aramid fiber. The maximum working pressure is 350 bar, and the burst pressure is 1400 bar. Thanks to its thermoplastic construction, polyester inner layer and polyurethane outer cover, the line can be used in appropriately selected hydraulic power systems for industrial, construction and agricultural machinery. The minimum bending radius is 50 mm.

Application in power hydraulic systems

The R8 DN06 thermoplastic hose is used in high-pressure hydraulic systems of construction, agricultural machinery and industrial equipment. It is designed for conveying appropriate synthetic and mineral oils and water-based hydraulic fluids. The choice of the line should take into account the working pressure, temperature, type of transported medium and installation requirements.

The 6 mm internal diameter allows the line to be used in circuits with an appropriately selected flow rate. When designing the installation, oil flow velocity, hose length and allowable pressure losses must be considered. The minimum bending radius of 50 mm allows for planning the hose path in limited assembly space while maintaining the required arc radius.

Construction with two aramid braids

The hose reinforcement consists of two braid layers made of very high-strength aramid fiber. Aramid is a material used in structures requiring high mechanical resistance with limited weight. Unlike traditional hydraulic hoses with steel braids, the R8 construction utilizes synthetic fiber reinforcement.

The working pressure of the line is 350 bar, while the burst pressure is 1400 bar, which corresponds to a 4:1 safety factor. Burst pressure is a strength parameter and must not be treated as the allowable operating pressure. The working pressure of the complete hose assembly also depends on the parameters of the fittings used and other connection elements.

Polyester core and polyurethane outer cover

The inner layer is made of polyester resistant to appropriate hydraulic oils, air and water-based fluids. The polyester core creates the medium flow channel, and two aramid braids provide pressure reinforcement. The outer polyurethane (PU) layer protects the line from oils, abrasion and weather conditions.

Despite the abrasion resistance of the polyurethane cover, avoid routing the hose over sharp edges and areas of intense friction. For assembly near moving machine parts, additional spiral guards for hydraulic hoses, appropriately selected for the line diameter, can be used.

Operating temperature and medium resistance

The R8 DN06 thermoplastic hose can work with appropriate hydraulic oils at temperatures from -40°C to +100°C. For air and water-based fluids, the maximum operating temperature is limited to +65°C. Distinguishing these values is important when selecting a hose for installations using various working media.

The hose can also be considered for applications with selected industrial gases, provided that material compatibility is confirmed and the line and fittings are approved for the specific gas, pressure and operating conditions. Application for gases should not result solely from hose parameters specified for hydraulic fluids.

Standards SAE 100 R8, SAE J517, ISO 3949 and EN 855

The hose belongs to the group of high-pressure thermoplastic lines of the SAE 100 R8 type. For this construction, SAE 100 R8, SAE J517, ISO 3949 and TSE11191 / EN 855 standards are indicated. These markings are essential for identifying the hose type and selecting the line for the technical requirements of the hydraulic system.

When replacing an R8 hose with another model, compare the working pressure, internal and external diameter, minimum bending radius, temperature range and reinforcement construction. R7, R8 type lines and rubber hydraulic hoses are not automatically interchangeable, even with the same nominal diameter.

Crimping fittings and preparing hydraulic lines

The R8 DN06 thermoplastic hose can be used to make complete hydraulic lines with appropriately selected fittings and ferrules. Assembly requires the use of components compatible with thermoplastic construction and crimping parameters specific to the particular set of hose, ferrule and fitting.

Do not automatically use ferrules or crimping parameters intended for rubber hydraulic hoses. HYDRON also offers custom-made crimped hydraulic hoses, prepared with appropriately selected assembly elements.

Frequently Asked Questions (FAQ)

What is the working pressure of the R8 DN06 thermoplastic hose?

The maximum working pressure is 350 bar, and the burst pressure is 1400 bar. Burst pressure is not the allowable operating pressure.

What reinforcement is used in the R8 DN06 hose?

The hose has two high-strength aramid fiber braids. This is not a steel-braided line.

What is the minimum bending radius of the DN06 R8 hose?

The minimum bending radius is 50 mm. During assembly, this parameter should be maintained and twisting the line around its own axis should be avoided.

Can the R8 DN06 hose be used with air and water-based fluids?

Yes, provided the medium and installation parameters are compatible. For air and water-based fluids, the maximum operating temperature is +65°C. In the case of industrial gases, additional confirmation of approval for a specific application is required.

What standards apply to the R8 DN06 thermoplastic hose?

The hose is marked with SAE 100 R8, SAE J517, ISO 3949 and TSE11191 / EN 855. These are important for identifying the construction and selecting the line for the hydraulic system.
