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.
Begin with 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.
The steel wire braided hydraulic hose is used to convey petrochemicals and hydraulic fluids in an environment with high pressure and high temperature. Steel wire hydraulic hose can be applied for various construction machines, such as exploiting machines, mining machines, agricultural machinery and etc.
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 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:
What Is 2 Wire Hydraulic Hose? (Double Wire Hydraulic Hose)
Compared with a 1 wire hydraulic hose, a 2 wire hydraulic hose is reinforced with 2 layers of stainless steel wire and can be also called a double braided hydraulic hose.
Here we have many 2-wire hydraulic hoses for you to select, and the 2-wire hydraulic hose is made of 2-layer steel wire as the reinforcement, to make the whole hydraulic hose much stronger.
Double wire braid hydraulic hose has the construction as follows, and double wire hose hydraulic hose is made of synthetic rubber lining, the synthetic rubber material is oil-resistant, and two-wire braided reinforcement is separated by synthetic rubber layer. The synthetic rubber cover is oil, fuel, weather, and abrasion-resistant.
By the way, the inner tube is much stronger than the cover, made of better synthetic rubber material, because the quality of the inner tube can determine the whole hydraulic hose.
The two wire hydraulic hose is the widely applied hydraulic hose for the hydraulic system on the hydraulic machine, and it is also the steel wire braided hydraulic hose, reinforced with the 2-wire layer in the middle.
So two-wire hydraulic hose is much stronger than the single-wire hydraulic hose, due to more steel wire. More wire layers can add strength and hardness to the whole hydraulic hose pipe, making it more durable for long-lasting service life.

Here are the 2-wire hydraulic hose below:
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.

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:
- Low-pressure applications
- Applications where flexibility is a priority
- Applications with moderate temperature fluctuations
2-Wire Hoses are ideal for:
