Thermoplastic hose TWIN R8 DN06 362 bar PREMIUM

The TWIN R8 DN06 PREMIUM thermoplastic hose is a twin hydraulic hose designed for parallel routing of two pressure lines in one organized bundle. Each line has a size of DN06, and the working pressure is 362 bar. The R8 design uses a thermoplastic core, two aramid fiber braids, and an outer polyurethane layer, thanks to which the hose combines high pressure resistance with low weight and good flexibility.

Technical parameters of the TWIN R8 DN06 hose

type: TWIN thermoplastic hydraulic hose,
version: twin, two parallel lines,
series: R8,
brand: PREMIUM,
size: DN06,
number of lines: 2,
working pressure: 362 bar,
core: thermoplastic polyester,
reinforcement: two aramid fiber braids,
outer layer: polyurethane,
operating temperature range: from -40°C to +100°C,
manufacturing standard: SAE 100R8 / DIN EN ISO 3949,
application: high-pressure hydraulic systems requiring parallel routing of two hoses.

What does the TWIN design mean?

TWIN means two hydraulic hoses routed in parallel as one set. This solution helps organize the installation and reduces the need for separate mounting of two single hoses.

In practice, the twin design is especially useful where two hoses are routed between the same installation points, for example as supply and return or two working lines controlling an actuator.

R8 two aramid braids

The R8 hose uses two braids made of aramid fiber. This material provides high strength at a much lower weight than classic steel reinforcement.

Thanks to this, R8 thermoplastic hoses work well in installations where, in addition to pressure, low weight, flexibility, and convenient hose routing are important.

Working pressure 362 bar

For this DN06 variant, the working pressure is 362 bar. This parameter should be referred to a single line of the TWIN hose, because the twin design consists of two parallel hydraulic hoses.

When making a ready hose assembly, remember that the allowable pressure of the entire set also depends on the fittings, ferrules, and crimping quality used.

Temperature range from -40°C to +100°C

The TWIN R8 family is designed to operate at temperatures from -40°C to +100°C. This allows the hose to be used both in low ambient temperatures and in typical hydraulic systems operating at elevated temperatures.

Polyurethane outer layer

The outer polyurethane layer provides a lightweight and mechanically resistant cover for the hose structure. Polyurethane is commonly used in thermoplastic hoses due to its good abrasion resistance and low weight.

When routing the hose in places exposed to intense friction, it is worth additionally using an appropriate protective cover.

Where are TWIN R8 hoses used?

TWIN R8 thermoplastic hoses are used in mobile machinery, automation, lifting equipment, control installations, and other hydraulic systems where parallel routing of two high-pressure hoses is required.

The twin design is especially convenient in space-constrained installations, as it helps organize the routing of hoses and reduce the number of separate mounting elements.

PREMIUM – a hose from the HYDRON offer

The PREMIUM designation is part of this product's name and identifies the line of hoses offered by HYDRON. The DN06 362 bar variant combines the R8 design with the TWIN solution, making it intended for demanding systems where simultaneously high strength and organized routing of two lines are essential.

What to pay attention to when assembling the hose?

Fittings, ferrules, and crimping parameters should be selected specifically for the R8 thermoplastic hose. Settings intended for 1SN, 2SN, 4SP, or 4SH rubber hoses should not be used solely based on a matching DN06 size.

With a TWIN hose, you should also plan the mutual orientation of both lines and fittings before performing the crimping, especially if the hose operates in an energy chain or tight enclosure.

Thermoplastic hose protection

If the hose operates in a place exposed to contact with the machine structure, it is worth using spiral hose guards, which reduce direct friction of the hose surface against installation elements.

HYDRON also produces custom crimped hydraulic hoses with the selection of appropriate fittings and crimping technology.

Thermoplastic hose TWIN R8 DN06 362 bar PREMIUM (1/4" twin)

The TWIN R8 DN06 362 bar PREMIUM thermoplastic hose is a specialized, double (twin) high-pressure hose designed to work in advanced power hydraulic systems where parallel operation of two pressure or supply-return lines is required. The PREMIUM class hose meets the strict requirements of international standards SAE 100 R8, EN 855 R8, and ISO 3949\. Two tubular-connected hoses with a nominal diameter of DN06 (1/4" – approx. 6.4 mm) are characterized by an allowable working pressure of up to 362 bar. Thanks to the use of an inner core made of polyester or polyamide, a double braid of synthetic (aramid) fibers, and an outer cover made of abrasion-resistant polyurethane (PU), the hose features low weight, negligible longitudinal deformation under pressure, and resistance to harsh environmental conditions. The TWIN R8 double hose is widely used in forklift masts, aerial work platforms, HDS loader cranes, working platforms, winches, as well as construction and industrial machinery.

Application, design and advantages of the TWIN R8 DN06 thermoplastic hose

The combined hydraulic routing in TWIN (twin) type hoses allows you to eliminate the problem of single hoses tangling on rollers and in chain energy chains of masts and telescopic booms.

Combined twin design (TWIN): Two hoses connected together form a compact and organized bundle, facilitating the routing of the installation on pulleys, rollers, and in machine chain guides.
High working pressure 362 bar: A double braid of high-strength synthetic yarn (aramid fibers) provides resistance to pressure spikes while maintaining a 4:1 safety factor (burst pressure is min. 1448 bar).
Polyurethane (PU) outer cover: It is characterized by very high resistance to abrasion, tearing, UV radiation, ozone, weather conditions, as well as oils and fuels.
Low weight and small bending radius: Thermoplastic hoses are lighter than traditional steel-braided rubber hoses, and the flexible polyurethane enables smooth hose routing on small-diameter rollers.
Wide operating temperature range: Resistant to continuous operation in the temperature range from -40°C to +100°C for hydraulic oils and up to +70°C for water-based and air-based fluids.

What to combine the TWIN R8 DN06 hose with and how to avoid assembly errors?

The TWIN R8 DN06 double thermoplastic hose (1/4" – inner diameter approx. 6.4 mm) works with professional crimpable components:

Dedicated fittings for thermoplastic hoses (R7 / R8): Standard metric (DKOL/DKOS, CEL/CES), inch BSP (DKR, AGR), JIC, and ORFS fittings made with a smaller tail thickness for the plastic core.
Crimp ferrules for thermoplastic hoses: Dedicated smooth ferrules without internal teeth (R7/R8 DN06 ferrules) that do not puncture the hard plastic core.
Crimping machines: The assembly of twin hoses is performed on service and production presses, which are hose crimping machines.
Dedicated fittings: A full selection of matching connectors is offered by hose crimping fittings.

When assembling twin hoses, remember that the thermoplastic core has different deflection and crush characteristics than a rubber hose. For crimping R8 hoses, dedicated ferrules for thermoplastic hoses and fittings without deep cuts on the tail should be used to avoid cutting the polyester core. You must also maintain the correct crimping dimension given in the manufacturer's table. Before separating the two lines at the ends of the installation, it is recommended to carefully cut the rubber-plastic joint without damaging the outer layer of the hoses.
