The SAE 100R8 / EN855 R8 thermoplastic hydraulic hose is designed for hydraulic systems that require high pressure resistance, lightweight construction, and flexible hose routing. It features an oil-resistant polyamide (PA) inner tube, high-tensile aramid fiber reinforcement, and a black polyurethane outer cover.
Compared with conventional rubber hydraulic hoses, this thermoplastic construction can offer a smaller outside diameter and lower weight for suitable applications. It is used in mobile machinery, material handling equipment, industrial hydraulic systems, and other equipment requiring reliable hydraulic fluid transmission.
Available in sizes from 1/4 inch to 1 inch, the hose has working pressure ratings ranging from 15 MPa to 38 MPa, depending on diameter. Its specified operating temperature range is -40°C to +100°C.
The seamless polyamide inner tube provides the internal passage for hydraulic fluid. Its oil-resistant properties make it suitable for compatible petroleum-based hydraulic fluids and other verified fluid types.
Fluid compatibility should be checked against the actual fluid formulation, concentration, and operating temperature.
One or two layers of high-tensile braided aramid fiber provide reinforcement for pressure hydraulic applications, depending on the hose configuration.
Aramid fiber reinforcement supports a lightweight hose structure while providing the strength required for the specified working pressure. The reinforcement configuration must match the applicable product rating and intended operating conditions.
The black polyurethane outer cover helps protect the hose against abrasion and normal external wear. Its flexible construction supports routing through equipment compartments where space and hose weight are important considerations.
The cover's resistance to weather, chemicals, and specific environmental conditions depends on the material formulation and actual operating environment.
The Honestflex SAE 100R8 / EN855 R8 hose range includes seven standard sizes. Working pressure, outside diameter, minimum bend radius, and weight vary by size.
Metric Size (mm) | Inch Size | SAE Dash Size | I.D. (mm) | O.D. (mm) | Tolerance (mm) | Working Pressure (MPa) | Working Pressure (PSI) | Minimum Burst Pressure (MPa) | Minimum Bend Radius (mm) | Weight (g/m) |

SAE 100R7 and SAE 100R8 are both thermoplastic hydraulic hose types, but they differ in their specified performance requirements and intended pressure applications.
Comparison Factor | SAE 100R7 | SAE 100R8 |
|---|---|---|
Hose Type | Thermoplastic hydraulic hose | Thermoplastic hydraulic hose |
Inner Tube | Thermoplastic material, depending on configuration | Oil-resistant PA for the listed Honestflex product |
Reinforcement | Synthetic fiber braid | High-tensile aramid fiber braid for the listed product |
Pressure Capability | Depends on size and applicable specification | Higher pressure ratings for the listed size range |
Typical Selection | Hydraulic systems meeting R7 pressure requirements | Hydraulic systems requiring the specified R8 pressure ratings |
Installation Considerations | Verify dimensions and bend radius | Verify dimensions, bend radius, and pressure rating |
The appropriate hose should be selected according to the system's maximum operating pressure, pressure surges, fluid compatibility, temperature, and installation requirements. A higher standard designation alone does not guarantee suitability for every application.
SAE 100R8 hose can be used in compatible hydraulic circuits in forklifts, aerial work platforms, lifting equipment, and other material handling machinery. Its lightweight construction can be advantageous where hose weight and routing space affect equipment design.
Suitable configurations can be used in hydraulic lines for construction equipment, agricultural machinery, and other mobile systems requiring the specified working pressure and temperature performance.
The hose can support compatible hydraulic fluid transmission in machine tools, hydraulic power units, and industrial control equipment. Final suitability depends on the selected size, fittings, pressure requirements, and fluid compatibility.
Thermoplastic hoses are also used in selected hydraulic tools and equipment where lightweight construction and flexible routing are beneficial. Applications involving electrical insulation require a separately verified non-conductive hose specification.
Standard SAE 100R8 construction should not automatically be assumed to be electrically non-conductive.
For applications such as aerial work platforms or equipment operating near electrical hazards, confirm that the specific hose is manufactured and tested to the required electrical insulation specification. The hose assembly, fittings, and installation must also meet the applicable safety requirements.
If electrical insulation is a key purchasing requirement, specify it clearly when requesting a quotation so the appropriate product configuration can be identified.
SAE 100R8 hydraulic hose is used to transmit hydraulic fluid in compatible medium- to high-pressure systems. Typical applications include mobile machinery, material handling equipment, industrial hydraulic controls, and selected hydraulic tools.
The listed Honestflex product uses an oil-resistant polyamide inner tube, one or two layers of braided aramid fiber reinforcement, and a black polyurethane outer cover.
The Honestflex product range has working pressure ratings from 15 MPa to 38 MPa, depending on hose size. Refer to the technical specification table for the rating of each diameter.
The listed operating temperature range is -40°C to +100°C. Actual suitability depends on the hydraulic fluid, pressure conditions, and the specifications of the complete hose assembly.
Not necessarily. Electrical insulation depends on the specific hose construction and verified test results. Confirm the non-conductive rating and applicable requirements before using a hose near electrical hazards.
Provide the required hose size, working pressure, hydraulic fluid type, operating temperature, hose length, order quantity, and destination market. If hose assemblies are required, include the connection type and fitting specifications.
