Hydraulic Products

Hydraulic hose is used to complete the connection and convey hydraulic fluid under pressure between components within a hydraulic system. They generally consist of rubber or elastomeric material reinforced with multiple layers of metal or textile and are covered with an outer layer of protective material. These are designed to give them the durability needed to withstand the pressures to which they are often subjected and the flexibility to fit into tight or confined spaces all while properly containing the fluid.

These components come in a variety of sizes and materials to suit the requirements and restrictions of a wide range of applications. They are also available with different fitting connector ends to accommodate different hydraulic systems.

Below we provide an overview of hydraulic hoses, outlining their functions, applications, types available, and the products available at Jason Industrial.

The primary purpose of a hydraulic hose is to move pressurized fluid within a hydraulic system to transmit force or energy to a point of application. Hydraulic systems are capable of both moving force within the system and using it to apply force or torque for the application.  In fact, they are capable of converting relatively low pressure into tons of output pressure with high precision and accuracy, which makes them particularly useful for moving and directing loads and providing the precise movement of mechanisms in equipment as well as propulsion.

Hydraulic hoses are chosen for their durability and flexibility. They must be durable enough to maintain their integrity in the face of high pressures and vibrations and flexible enough to align with the system’s ports easily. Additionally, hydraulic systems are often a safer option than electrical systems in explosion-prone environments.

Hydraulic systems have both rigid and flexible fluid conveying components. The rigid tubes may be are used to transfer hydraulic fluid in confined spaces with little room for movement, while the flexible hose is generally incorporated as connections that allow system components and tools to move freely. For example, the use of properly applied flexible hydraulic hose in an assembly system allows for movements with full motion and flexibility compared to rigid tubes.

Some of the industries that regularly employ hydraulic hoses include:

• Agriculture
• Automotive
• Construction
• Manufacturing
• Mining
• Oil and gas

Hydraulic hoses find application in a wide range of devices, equipment, and systems, such as:

• In the agricultural industry: combines, harvesters, tractors, and tillage equipment
• In the automotive industry: production lines and service
• In the construction industry: bulldozers, excavators, and mixers
• In the manufacturing industry: assembly lines, mills, and presses
• In the mining industry: drills, excavators, and longwall miners
• In the oil and gas industry: cranes, drill rigs, and fluid transfer systems

Hydraulic hose is engineered to meet the needs of particular applications. For this reason, the design and construction of the three main components—inner tube, reinforcement and outer covering—often differ from one hose to the next.

As the inner tube component of a hydraulic hose comes in direct contact with the fluid in a hydraulic system, it is important to consider whether its construction material and the hydraulic fluid are chemically compatible. Some of the most common materials used for inner tubes are flexible rubber polymers such as nitrile (NBR), chlorinated polyethylene (CPE) and thermoplastics, and fluorocarbons such as PTFE). The proper choice of material depends on the expected operating temperatures and fluids. Nitrile tube is generally excellent for most petroleum-based hydraulic fluids, but is not suitable for very high continuous temperatures approaching 300 degrees F.  CPE materials generally provide excellent high temperature performance at this level.

The reinforcement component of a hydraulic hose consists of braided or spiral-wound metal wire or textile yarn. This layer provides support to the inner tube, preventing it from bending, bulging, or breaking and managing to contain the working pressures seen to the hose’s maximum pressure rating.

The outer layer of a hydraulic hose is typically made from a durable material such as synthetic rubber or textile cover.  Various rubber materials may be used in the hose’s design to best meet the abrasion and flexibility requirements that may be needed.  It is intended to protect the reinforcement layers from exposure to moisture, corrosive chemicals, abrasion, and other environmental factors. Jason Industrial offers Dreamshield® protective rubber cover, which are designed for superior exterior hose protection. The covering is made from a durable rubber compound that exhibits six to eight times the abrasion resistance of traditional cover materials.

When selecting a hydraulic hose for an application, there are several factors to consider ensuring the chosen product performs as intended. The term “STAMPED” serves as an appropriate mnemonic device:

• S — Size: Verify the inner diameter and length required to select a hydraulic hose that will maintain constant and reliable system pressure without the risk of overloading the system or losing pressure. Use the Jason sizing nomograph to allow proper size selection for maximum life on any new system design.
• T — Temperature: Consider the temperature range of the internal hydraulic fluid and external environment to which the hose will be exposed. The hose materials must be able to withstand the highest and lowest operating temperatures.
• A — Application: Analyze the application for which the hose assembly will be used. Some applications will require more flexibility or durability.
• M — Material: Identify the chemical properties of the hydraulic fluid and environment. It is important to use compatible materials for the inner tube, as well as the other components of the hydraulic assembly, including covers, seals, and fasteners.
• P — Pressure: Establish the typical maximum operating pressure of the system and any potential for pressure fluctuations. The hose must be able to withstand the highest and lowest operating pressures while recognizing the frequency and magnitude of any surges in the system.
• E — Ends: Determine the end connections required. The connection must connect properly with the system ports to prevent leakage and other performance issues.
• D — Delivery: Ascertain how many hoses are required and when they should be delivered.
