We are the hydraulic hose manufacturer to provide multiple types of hydraulic hose in the market. Today I am here to share with you guys about the 2-wire hydraulic hose.
In this guide, I am happy to share with you all about the steel wire hydraulic hose, including steel wire braided hydraulic hose and steel wire spiral hydraulic hose.
2-Wire Hydraulic Hose Structure

The hydraulic hose is structured with three different parts, inner tube, reinforcement, and outer cover. The wire is used to create the reinforcement layer of the hydraulic hose. And here are two types of hydraulic hose, based on the manufacturing craftsmanship, they are spiral hydraulic hose and braided hydraulic hose. And spiral & braided hydraulic hose is basically different in the reinforcement.
A 2-wire hydraulic hose structure is designed to handle medium to high-pressure hydraulic applications, and its construction typically includes the following layers:
- Inner Tube (Core):
This is the innermost layer that comes into direct contact with the hydraulic fluid. It’s usually made from synthetic rubber or thermoplastic materials, chosen for their compatibility with various hydraulic fluids and their ability to withstand the fluid’s temperature and chemical properties.
- First Reinforcement Layer (Wire Braid):
This layer consists of a woven or braided layer of high-tensile steel wire. It provides the initial structural support, helping the hose withstand internal pressure.
- Second Reinforcement Layer (Wire Braid):
An additional layer of high-tensile steel wire braiding, interwoven over the first layer. This second layer further enhances the hydraulic hose’s strength and pressure-bearing capacity, significantly increasing its overall durability.
- Outer Cover (Jacket):
The outermost layer, typically made from synthetic rubber or another abrasion-resistant material. It protects the reinforcement layers from external damage, such as abrasion, weathering, and chemical exposure. This layer also contributes to the hose’s overall flexibility and durability.
And the braided hydraulic hose can be classified into 1 wire braided hydraulic hose, 2 wire braided hydraulic hose, 3 wire braided hydraulic hose, 4 wire braided hydraulic hose, 6 wire braided hydraulic hose and etc. And the hydraulic hose with 1 wire reinforcement can work well in very low to high temperatures with the range of -40ยฐC to +100ยฐC, and even the maximum temperature can be up to +125ยฐC.
Here, the hydraulic hose reinforcement is made of steel wire, with different layers to create different strengths, and more wires can be added much more strength to the whole hydraulic hose.
And we have different wire layers as the reinforcement to make braided hydraulic hoses.
- 1 wire hydraulic hose (wire braided hydraulic hose)
- 2 wire hydraulic hose (wire braided hydraulic hose)
- 4 wire hydraulic hose (wire spiral hydraulic hose)
- 6 wire hydraulic hose (wire spiral hydraulic hose)
It’s flexible for you to choose the proper wire braided hydraulic hose for your hydraulic project.
What Does 2 Wire Mean on a Hydraulic Hose?
When a hydraulic hose is described as “2 wire,” it refers to the hydraulic hose’s reinforcement layer, specifically indicating that it has two layers of wire braiding. This reinforcement is crucial for the hose’s ability to withstand high pressures. The wire braiding is typically made of steel and is interwoven around the inner tube of the hose, providing structural integrity and preventing the hose from expanding or bursting under pressure.
The two layers of wire braiding provide increased strength compared to hoses with single wire braiding or textile reinforcement. This makes 2-wire hoses suitable for medium to high-pressure hydraulic applications.
The specific pressure rating of a 2-wire hose will vary depending on the wire’s gauge, the braid’s pattern, and the hose’s overall construction, but it generally signifies a robust and durable hose capable of handling demanding hydraulic tasks.
What Is 1 Wire Hydraulic Hose? (Single Wire Hydraulic Hose)

1 wire hydraulic hose, also called 1-wire braided hydraulic hose, single wire hydraulic hose, is the braided hydraulic hose reinforced with one layer of stainless steel wire. The single wire braided hydraulic hose๏ผ made of oil-resistant synthetic rubber material with a single layer of steel wire reinforcement.
You can get to know if a hydraulic hose is a 1 wire hydraulic hose, by reading from the hydraulic hose cover printing mark. This EN857 1SC is the 1 wire hydraulic hose.
Here are 1 wire hydraulic hose below:
3/8 2 Wire Hydraulic Hose
A 3/8 2-wire hydraulic hose refers to a hose with an inner diameter (ID) of 3/8 inch and two layers of high-tensile steel wire braiding for reinforcement. This configuration is designed to handle medium to high-pressure hydraulic applications, providing a balance of flexibility and strength. The 3/8-inch ID is suitable for applications requiring moderate fluid flow, while the 2-wire reinforcement ensures the hose can withstand significant pressure without expanding or bursting.

2 Wire Hydraulic Hose Rating
2-wire hydraulic hoses are known for their higher pressure ratings compared to 1-wire hoses. The specific pressure rating can vary depending on the exact type and size of the hose. However, they typically handle pressures in the range of 3,000 to 6,000 PSI.
It’s important to note that the pressure rating is just one factor to consider when selecting a hydraulic hose. Other factors include:
- Temperature range: 2-wire hoses generally have a wider temperature range than 1-wire hoses.
- Flexibility: 2-wire hoses are typically less flexible than 1-wire hoses.
- Weight: 2-wire hoses are generally heavier than 1-wire hoses.
- Cost: 2-wire hoses are generally more expensive than 1-wire hoses.
When selecting a hydraulic hose, it’s important to consider all of these factors to ensure that the hose is suitable for the specific application.
1 Wire vs 2 Wire Hydraulic Hose
The primary difference between 1-wire and 2-wire hydraulic hoses lies in their construction and resulting capabilities.

When to Use Which Wire Hydraulic Hose?
The choice between 1-wire and 2-wire hoses depends on the specific application and its requirements.
1-Wire Hoses are suitable for:
