Discover the Purpose, Types, and Selection Process for the Perfect Hydraulic Hose
Hydraulic hoses may not be that popular in the world of many, but they are major players in the daily operations of a wide range of industries. In the following, we’ll look into the world of hydraulic hoses, covering their purpose, types, and guidelines for choosing the perfect fit for various applications.
So What Are Hydraulic Hoses?
Hydraulic hoses are specialised types of hose found in a number of both commercial and industrial machines, applications and environments. They are usually made from flexible rubber or wire, with a multi-layered structure, that contains
- an inner tube,
- a reinforced laye
- and of course an outer layer
The way this is made makes it so strong and durable that it is perfect for its intended use.
The Vital Role of Hydraulic Hoses
Hydraulic hoses direct the flow of hydraulic fluid between other parts in the hydraulic system it serves. They make sure there is a seamless operation of the entire system during its consistent use. However a faulty hydraulic hose can lead to disruptions in production lines and temporarily incapacitate essential machinery until a replacement is installed.
Industries Relying on Hydraulic Hoses
Many industries, such as the following:-
. . . they all depend on hydraulic hoses and can be found in various applications, including like the following also:-
- factory production lines
- fleet vehicles
- construction machinery
- and commercial farming

Here is some information outlining a representation of the various hose types and their uses.
Main Category: Applications
- Braided Hose: General industrial applications, petroleum or water-based fluids, operating temperatures from -40°C to 100°C
- Multi-Spiral Hose: Heavy-construction, high pulse applications, mineral and hydraulic oils, emulsions of water and oil, construction, civil engineering, mining, quarrying, oil industries, agriculture
- Low-Pressure Hose: Anti-static delivery, air, lube, or return lines, lighter applications
- Stainless Steel Wire-Braided Hose: Aggressive applications, transfer of chemical substances, extreme temperature and pressure conditions, vacuum
- Thermoplastic Hydraulic Hose: Lift equipment, lubrication lines with a small outside diameter, operating at very low temperatures, abrasion-resistant
Diving into the Different Types of Hydraulic Hoses
Hydraulic hoses can be put into two categories: those that are linked with SAE (Society of Automotive Engineers) standards in the USA and EN (European Norm) standard hydraulic hoses.
When it comes to hydraulic hoses, EN standards define the dimensions, performance characteristics, and other specifications for these hoses, similar to the Society of Automotive Engineers (SAE) standards. By keeping to EN standards, manufacturers can rest assured that their hydraulic hoses are compatible and meet the required safety and performance levels across Europe.
These standards also help consumers and businesses to select the right hydraulic hoses for their applications, knowing that they meet the necessary criteria established by the European Committee for Standardization.
SAE hydraulic hoses are widely used within the UK and are considered the industry benchmark. They are available in 16 different types, each adhering to strict dimensions and performance characteristics.
SAE International has developed standards for various hydraulic hoses to ensure consistent quality, safety, and performance across the industry. The 16 types of hydraulic hoses within the SAE remit are based on their construction and pressure rating.
They are classified under the following categories:
- SAE 100R1: This is a single steel wire braid hose suitable for medium pressure hydraulic lines.
- SAE 100R2: A double wire braid hose that works well for high-pressure hydraulic oil lines.
- SAE 100R3: A textile-braided, low-pressure hose used for hydraulic oil, fuel, and water-glycol antifreeze solutions.
- SAE 100R4: This is a suction and return line hose for low-pressure hydraulic applications.
- SAE 100R5: A medium pressure, textile-covered, single wire braid hose used for hydraulic and pneumatic applications.
- SAE 100R6: A single textile braid hose for low-pressure hydraulic oil, gasoline, and water.
- SAE 100R7: A medium-pressure thermoplastic hose with a synthetic fiber reinforcement, suitable for hydraulic and pneumatic systems.
- SAE 100R8: A high-pressure thermoplastic hose with a synthetic fiber reinforcement, designed for hydraulic systems.
- SAE 100R9: A high-pressure, four-spiral wire hose used for hydraulic systems.
- SAE 100R10: A high-pressure, four-spiral wire hose that can handle high-impulse hydraulic applications.
- SAE 100R11: A six-spiral wire hose for extremely high-pressure hydraulic applications.
- SAE 100R12: A four-spiral wire hose suitable for high-pressure hydraulic oil systems.
- SAE 100R13: A multi-spiral wire hose designed for very high-pressure hydraulic applications.
- SAE 100R14: A PTFE-lined, stainless steel wire reinforced hose for high-temperature hydraulic applications.
- SAE 100R15: A six-spiral wire hose for extremely high-pressure hydraulic systems.
- SAE 100R16: A compact, two-wire braid hose for high-pressure hydraulic applications.
These 16 SAE hose types have specific performance characteristics and are designed to meet various pressure and temperature requirements in hydraulic applications.
The main categories of hose that many are privy to are as follows:-
- Braided hose: Commonly used in general industrial machinery, these high-pressure hoses are available in what is known as one, two, or three braided steel wires. They are compatible with petroleum or water-based fluids and operate in temperatures ranging from -40°C to 100°C.
- Multi-spiral hose: Known for its flexibility, this hose’s internal configuration makes it ideal for heavy-construction and high pulse applications. It is typically used to transfer mineral and hydraulic oils or emulsions of water and oil, making it suitable for industries like construction, civil engineering, mining, quarrying, oil, and agriculture.
- Low-Pressure Hose: Featuring a textile-braided design, this hose is highly flexible but not suitable for higher pressures. It is commonly used in lighter applications such as anti-static delivery, air, lube, or return lines.
- Stainless Steel Wire-Braided Hose: Durable and heavy-duty, these hoses are braided with single or double stainless steel wire and are ideal for aggressive applications like chemical substance transfer. They can withstand extreme temperature and pressure conditions, even in a vacuum.
- Thermoplastic Hydraulic Hose: Comprising two layers of thermoplastic material separated by a middle reinforcement layer made of wire or synthetic fibres, these hoses can operate at very low temperatures and are highly resistant to abrasion. They are popular in hydraulic-powered lift equipment and lubrication lines where a small outside diameter is needed.
Choosing the Perfect Hydraulic Hose
When you are picking the right hydraulic hose for your system its a good idea to talk to a professional who specialises with such and who can source or design the most appropriate hose for your requirements. Things you take into consideration that affect the type of hydraulic hose you need include:
- The type of fluid passing through the hose
- The operating conditions (pressure/temperature)
- Hose size (diameters and length)
- Hose flexibility and durability
- Ends and couplings (what the hose will be attached to)
