Hydraulic hose for hot oil ULTIMATE 1SN DN40 1 1/2"

Single-braid (1SN) ULTIMATE hydraulic hose 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 industries and branches of the economy. The 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, momentarily 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 pinprick leaks. The 1SN hose can be replaced by hose with two steel braids ( higher pressure resistance ). For crimping single-braid hoses, we recommend 1SN crimp ferrules, dedicated to it or universal sleeves. The 1SN hose is a hose whose surface is wrapped

Construction of a single-braid hose :

Inner layer : Black synthetic rubber resistant to oils, hot oil up to +135°C, periodically up to +150°C
Reinforcement : One high-strength steel wire braid.
Outer layer : Blue synthetic rubber resistant to abrasion, oils, weather conditions, and ozone.

Application of 1SN hoses :

Hydraulic hoses with one steel braid can be used for:
hydraulic fluids compliant with ISO 6743-4, except for HFD R, HFD S, HFD T (from -40C to +100C)
water (from 0°C to +80C),
compressed air (from 0°C to +135°C).

The hose has a QUALITY CERTIFICATE !

The hose comes in original coils/rolls of 50m (smaller quantities can be ordered)

Hoses cut to customer request in any quantity (cut hoses are non-returnable), returns are only possible for full rolls - price per 1 running meter.

Hydraulic hose DN40 1SN 50 bar Ultimate 135°C

The DN40 1SN 50 bar Ultimate 135°C hydraulic hose is a flexible high-pressure line designed for operation in power hydraulic systems with high flow rates and moderate working pressure. The DN40 designation specifies a nominal diameter of 40 mm, while the 1SN symbol informs about the use of a single steel braid as a reinforcing layer. The maximum working pressure is 50 bar, and the increased temperature resistance up to 135°C allows for safe operation in installations where the working medium reaches high temperatures. It is a solution dedicated to users expecting parameter stability, aging resistance, and high operational durability.

Technical definition and compliance with standards

The DN40 1SN hydraulic hose is manufactured according to the requirements of the EN 853 1SN standard and corresponds construction-wise to the SAE 100R1AT standard. The construction includes an internal layer of synthetic rubber resistant to hydraulic oils, a single steel braid providing pressure strength, and an external cover resistant to abrasion, weather factors, and oil action. The 1SN design ensures adequate flexibility while maintaining the required strength for 50 bar pressure. The Ultimate 135°C version stands out with increased thermal resistance compared to standard 1SN hoses, whose typical operating temperature is up to 100°C. Thanks to this, the line can be used in industrial, agricultural, and technological installations operating at elevated temperatures.

Application in power hydraulics and industry

The DN40 1SN 50 bar hydraulic hose finds application in systems where high medium flow at relatively low working pressure is crucial. It is used in return lines of power hydraulics, in agricultural machinery, in industrial devices, and in technological oil transport systems. The DN40 diameter limits pressure losses at high flow rates, which translates into effective operation of the entire system. In combination with properly selected 1SN hose fittings and professional crimping of hydraulic lines it is possible to create a durable and tight working line tailored to a specific application.

Differences compared to other 1SN and 2SN hoses

Compared to standard 1SN hoses, the Ultimate 135°C version provides greater temperature resistance and better parameter stability during long-term operation at high temperatures. In relation to 2SN hoses, the DN40 1SN model has a single steel braid, which means lower resistance to very high pressures, but at the same time greater flexibility and lower weight of the line. At a working pressure of 50 bar, the single-braid construction is fully sufficient and allows for optimizing the cost of the entire hydraulic line. The choice between 1SN and 2SN should always be based on an analysis of the maximum pressure, the nature of the system's operation, and the temperature of the medium.

Common mistakes in DN40 1SN hose selection

The basic error is selecting a line based solely on the DN40 diameter without considering the actual working pressure and operating temperature. It is always necessary to check whether the 50 bar and 135°C parameters correspond to the installation conditions. Another problem is the use of incorrect sleeves and fittings not dedicated to 1SN hoses, which can lead to leaks or damage to the connection. It is also important to maintain the minimum bending radius during installation, as excessive bending of the DN40 line shortens its lifespan and can cause premature failure.
