PREMIUM 4SH DN25 1" 380 bar hydraulic hose - 20m roll

What is the 4SH DN25 1" 380 bar hydraulic hose

The PREMIUM 4SH DN25 1" 380 bar hydraulic hose is a high-pressure hose designed for operation in demanding power hydraulics systems, where resistance to very high pressure and intensive exploitation is crucial. This type of hose belongs to the four-braid hose class, which means the use of four layers of steel braid, providing exceptional mechanical strength and resistance to pressure pulsations. The product is used wherever standard 2SN hoses prove insufficient, especially in installations with high dynamic loads. In practice, this means working in construction machinery, industrial equipment, and mobile hydraulics, where the working medium is transported under high pressure and in variable conditions. In the Hydron offer, this hose is a solution for professionals who expect reliability, durability, and compliance with international standards.

Design and construction of the 4SH hose

Construction of the 4SH DN25 hydraulic hose has been designed for maximum strength and long life even in the most demanding operating conditions. The inner core is made of high-quality synthetic rubber resistant to hydraulic oils, which ensures chemical stability and no material degradation during long-term contact with the working medium. The reinforcement layer consists of four spiral steel braids, which are responsible for transferring high operating pressures reaching 380 bar. It is this construction that distinguishes the 4SH series from standard hydraulic hoses and makes this product the choice for the most demanding applications. The outer cover is made of abrasion and weather-resistant synthetic rubber, which protects the hose against mechanical damage, oils, greases, and the influence of UV radiation. Thanks to this, the hose can be used in both indoor and outdoor installations.

Operating principle in the hydraulic system

The 4SH hydraulic hose functions as a conduit transporting the working medium, most often hydraulic oil, between system components such as pumps, hydraulic control valves, or actuators. Its task is to ensure a tight and safe flow of the medium under high pressure without energy loss. Thanks to the use of a multi-layer steel braid, the hose effectively compensates for vibrations and pressure pulsations, which are a natural phenomenon in power hydraulics. Proper construction also allows for maintaining flexibility while keeping high resistance to stretching and bending. In practice, this means stable operation of the entire hydraulic system and reduction of the risk of failures that could lead to machine downtime.

Norms and technical standards

The 4SH type hydraulic hose is manufactured in accordance with international standards that specify its technical parameters and quality requirements. The most common standards for this product class are EN and ISO norms, which define, among others, resistance to pressure, temperature, and service life. The 4SH norm refers to the four-braid construction, which means a higher strength class compared to standard 1SN or 2SN type hoses. Thanks to this, the user is assured that the product meets the requirements of professional hydraulic installations. Compliance with standards is also a guarantee of compatibility with components such as hydraulic fittings and hose crimp ends.

Application of the 4SH DN25 hydraulic hose

The Semperit 4SH DN25 hydraulic hose finds wide application in many industrial sectors. It is commonly used in construction machinery such as excavators, loaders, or bulldozers, where high performance parameters are required. In agriculture, it is used in tractors and agricultural machinery, where hydraulic systems are responsible for controlling attachments. In the manufacturing industry, this hose is used in processing lines and hydraulic presses. The product also finds application in power hydraulic services, where it is used for the production of custom-made hydraulic hose assemblies. Thanks to its high resistance to operating conditions, it performs perfectly in mobile and stationary applications.

Differences compared to other hydraulic hoses

The 4SH DN25 hose differs significantly from popular hose types such as 2SN. The main difference lies in the number of steel braid layers, which translates directly into higher operating pressure and greater resistance to mechanical damage. Compared to hoses 1SN and 2SN, the 4SH model is less flexible but much more durable. This means it should be used in places where durability is the priority, rather than a minimum bend radius. Differences also concern the application; 4SH hoses are designed for operation in extreme conditions, while lighter hoses are used in less demanding installations.

Most common errors in hydraulic hose selection

One of the most common errors is choosing a hose with an operating pressure that is too low relative to the installation requirements. In practice, this leads to rapid wear of the hose or even its damage. Another problem is the incorrect selection of the DN diameter, which can cause pressure drops and incorrect operation of the hydraulic system. It is also important to match the appropriate fittings and connectors to ensure the tightness of the connection. A frequently encountered error is also ignoring the operating temperature and the type of working medium, which can lead to material degradation.

FAQ

How to choose the right 4SH hydraulic hose? Selection should take into account operating pressure, DN diameter, and operating conditions, including temperature and type of medium.
