Medium Pressure Hydraulic Hoses

Medium pressure hydraulic hoses are used to transfer hydraulic fluid between pumps, valves, cylinders and other components in systems that require a suitable balance of pressure capacity, flexibility and durability. They are commonly considered for industrial machinery, mobile equipment, material handling systems and general hydraulic applications.

Choosing the right hose involves more than matching the connection size. The hose must suit the system’s maximum working pressure, fluid type, operating temperature, movement and installation conditions. Hydrofit Engineers supplies a range of hydraulic hose types for different industrial requirements, including SAE 100 R1, R2, R3, R5 and R6 hose families listed on its hydraulic hose range page.

Types of Medium Pressure Hydraulic Hoses

The suitable hose construction depends on the application and the required operating conditions. Common hose families to consider include the following.

SAE 100 R1 Hydraulic Hose

SAE 100 R1 hoses use a single steel wire braid reinforcement in the applicable construction. They are used in hydraulic circuits where the specified working pressure, hose size and operating conditions match the hose rating.

SAE 100 R2 Hydraulic Hose

SAE 100 R2 hoses use double steel wire braid reinforcement in the listed SAE 100 R2 AT construction. They are considered for hydraulic lines that require a higher pressure capability than a comparable single-wire-braided design. The working pressure varies with hose diameter, so the correct size-specific specification must be checked before selection.

SAE 100 R3 Hydraulic Hose

SAE 100 R3 is a textile-reinforced hose family used in applications suited to its particular pressure rating and construction. It should be selected according to the system’s requirements rather than treated as interchangeable with steel wire-reinforced hoses.

SAE 100 R5 Hydraulic Hose

SAE 100 R5 is a textile-covered, wire-reinforced hose design commonly associated with particular hydraulic and transmission applications. Confirm the applicable specification and intended service before ordering.

SAE 100 R6 Hydraulic Hose

SAE 100 R6 uses a textile-reinforced construction and is intended for applications within its rated pressure range. Hydrofit’s listed R6 specifications include a synthetic rubber inner tube and a single high-tensile yarn braid, with pressure ratings varying by size. See the SAE 100 R6 hydraulic hose specifications for the published model details.

Technical Specifications

The following table outlines the key parameters to check when selecting a medium pressure hydraulic hose. Exact values should be entered from the datasheet for the specific model and diameter.

Parameter	Specification to confirm
Hose type	SAE 100 R1, R2, R3, R5 or R6, as applicable
Nominal bore	Available inside diameters by model
Outside diameter	Model- and size-specific
Reinforcement	Steel wire braid or textile reinforcement, depending on hose type
Working pressure	Rated value for the selected diameter
Burst pressure	Manufacturer-published value for the selected diameter
Minimum bend radius	Model-specific minimum
Temperature range	Based on hose construction and fluid compatibility
Inner tube	Confirm material and compatibility with the hydraulic fluid
Outer cover	Confirm cover material and environmental resistance
End connections	Suitable fittings, thread type and assembly method

Important: Do not use burst pressure as the normal operating pressure. Select the hose using its rated working pressure and the system’s operating conditions.

Applications of Medium Pressure Hydraulic Hoses

Medium pressure hydraulic hoses may be suitable for applications such as:

General industrial hydraulic circuits
Agricultural and material handling equipment
Hydraulic lines in mobile machinery
Machine tools and manufacturing equipment
Hydraulic systems where flexibility is required around moving components
Selected return, supply and control lines, where the hose rating is appropriate

The actual application suitability depends on the hose model, pressure rating, fluid and operating environment.

How to Select the Right Medium Pressure Hydraulic Hose

Before ordering, check these details:

Working pressure: Consider normal operating pressure, pressure peaks and the system’s requirements.
Hose bore: Match the internal diameter to the required flow rate and acceptable pressure drop.
Fluid compatibility: Confirm that the inner tube is compatible with the hydraulic oil or other fluid.
Temperature: Check both the fluid temperature and the surrounding environment.
Bend radius and movement: Avoid tight bends, twisting and excessive movement at the hose ends.
Fittings and assembly: Match the hose with compatible end fittings and the specified crimping procedure.

For a complete connection, also review Hydrofit’s range of hydraulic hose fittings. The hose and its fittings must be compatible and correctly assembled for the intended pressure.
