Hydraulic hose ULTIMATE 1SN DN50 ( 2" )

Single-braid hydraulic hose (1SN) ULTIMATE reinforced with one wire braid inside the hose. One of the best hoses available on the Polish market. The hose has a quality certificate. The hose can be used in all sectors and branches of industry. Hoses exceed the EN853 1SN standard, meet the ISO 18752 BC standard, impulse 500,000 cycles. 1SN hoses have a smaller bending radius and are more flexible than 2SN hoses. The hose consists of an inner tube made of special synthetic rubber resistant to hot oil up to +135°C temporarily up to +150°C ., reinforcement of one steel braid and a durable outer cover made of special synthetic rubber resistant to oils, abrasion, weather conditions and pinhole leaks. The 1SN hose can be replaced by a hose with two steel braids ( higher pressure resistance ). For crimping single-braid hoses, we recommend 1SN crimp ferrules, dedicated to it or universal ferrules. The 1SN hose is a hose with a wrapped surface.

What is a DN50 1SN 40 bar hydraulic hose?

The DN50 1SN 40 bar hydraulic hose is a flexible high-pressure line designed for operation in power hydraulics systems and installations transporting hydraulic oil. The DN50 designation indicates a nominal internal diameter of 50 mm, while the 1SN symbol refers to a construction compliant with the EN 853 1SN standard, which is a single steel braid hose. The maximum working pressure is 40 bar, and the permissible operating temperature reaches 135°C. This type of hose is used where a large medium flow cross-section is required at moderate working pressure. Thanks to its solid construction and temperature resistance, it is used in industrial, agricultural installations and in construction machinery.

Construction and operating principle

The DN50 1SN 40 bar hydraulic hose is built of three basic layers. The inner layer is made of oil-resistant synthetic rubber, which ensures tightness and compatibility with hydraulic oils and petroleum-based working fluids. The reinforcing layer is a single steel braid, which is responsible for transferring pressure loads and protects the hose from bursting. The outer rubber cover protects against abrasion, weather factors and mechanical damage. The principle of operation is simple: the medium under pressure flows through the flexible line, and the steel braid stabilizes the structure, limiting its expansion under pressure. Thanks to this, control over the flow and the operational safety of the entire system are maintained.

EN 853 1SN standard and operating parameters

The DN50 1SN 40 bar hydraulic hose is manufactured in accordance with the EN 853 1SN standard, which specifies requirements for construction, pressure resistance and impulse tests. This standard defines hoses with one steel braid intended for medium and lower working pressure ranges. The operating temperature up to 135°C allows the use of this line in installations where hydraulic oil reaches elevated temperatures. It should be remembered, however, that the medium temperature and ambient conditions affect the durability of the line and should be taken into account during selection.

Practical application

The DN50 1SN 40 bar hydraulic hose is used in supply installations with high oil flow, in medium return systems, in hydraulic power units and in heavy industry. The large DN50 diameter allows the transport of significant amounts of liquid with limited pressure losses. It is also used in agricultural and construction machinery, where a flexible line with a large cross-section and resistance to external conditions is required. It can be crimped using appropriate hydraulic fittings and crimp ferrules available in the Hydron offer.

Differences between 1SN, 2SN and 4SP

The 1SN hydraulic hose has one steel braid and is designed for operation at lower pressures than 2SN or 4SP hoses. The 2SN version has two steel braids, which significantly increases pressure resistance, while 4SP is a spiral construction intended for very high pressures. In the case of DN50 and 40 bar pressure, the 1SN construction is an optimal solution, providing appropriate strength without excessive stiffening of the line. Choosing a hose with a higher pressure class than required may generate unnecessary costs and make installation difficult.

Most common selection errors

One of the most common errors is selecting a hose solely based on diameter, without considering the working pressure and operating temperature. In the case of DN50 1SN, the maximum working pressure is 40 bar and should not be exceeded. Another error is not considering the minimum bending radius, which has a direct impact on the line's durability. Running the hose too tightly can lead to damage to the steel braid and shortened service life. At Hydron we provide technical advice in the range of selecting hydraulic hoses, fittings and crimping technology, so that the installation is safe and durable.

Why is it worth ordering from Hydron?

FAQ

How to choose a DN50 1SN 40 bar hydraulic hose?
You should consider the DN50 internal diameter, maximum working pressure of 40 bar and operating temperature up to 135°C. It is also important to check the minimum bending radius.

Is the DN50 1SN hydraulic hose suitable for high pressure?
No. The 1SN construction is intended for lower and medium pressures. For higher parameters, 2SN or 4SP should be considered.

What is the price of a DN50 1SN 40 bar hydraulic hose?
The current price is available on the product page in the Hydron store. For larger orders, an individual quote is possible.

Can I order the DN50 1SN hose in a crimped version?
Yes. Hydron offers a professional hydraulic hose crimping service along with the selection of appropriate fittings.
