In the field of construction machinery, high-pressure rubber hoses, as an important transmission medium, bear the important task of transmitting hydraulic oil. However, different application scenarios have different requirements for hoses. In order to meet the needs of use in various complex environments, LETONE high-pressure rubber hose products came into being. With its excellent performance and wide range of applications, this hose has become an ideal choice for large construction machinery such as excavators and harsh environments.
LETONE high-pressure rubber hose uses nitrile or chloroprene synthetic rubber as the inner rubber layer. This material has good oil resistance and can be used with biodegradable hydraulic oil. In terms of reinforcement, the hose is braided with one or two layers of steel wire, with diameters ranging from 1/4" to 3/8", and can be pulsed up to 300,000 times. In addition, the hose wound with four layers of steel wire has a pulse count of up to 1 million times, fully demonstrating its excellent pressure resistance and stability.
In addition to the careful design of the inner rubber layer and reinforcement layer, the appearance of LETONE high-pressure rubber hose is also quite distinctive. The outer rubber layer of the standard pipe is made of non-peeling, wear-resistant and weather-resistant synthetic rubber, which not only ensures the durability of the hose, but also gives it good anti-aging properties. The wear-resistant pipe and super wear-resistant pipe have further upgraded the material of the outer rubber layer, using non-peeling highly wear-resistant and weather-resistant synthetic rubber and peel-free ultra-wear-resistant and weather-resistant UHMWPE materials respectively. These materials have higher durability. Abrasive and protective properties, it can effectively protect hoses from wear and external factors.
LETONE high-pressure rubber hose also has a wide operating temperature range and can be used between -40℃ to +100℃. Models from -40℃ to +121℃ are also available. This feature allows the hose to work normally in extremely cold or extremely hot conditions, meeting the needs of use in various extreme environments.
In addition, the low bending radius design of LETONE high-pressure rubber hose is also one of its highlights. Compared with ISO18752 standard and SAE standard, the bending radius of LETONE high-pressure rubber hose is reduced by 30% and 38% respectively. This design makes the hose more flexible and convenient during installation and use, reducing the risk of damage caused by excessive bending.
It is worth mentioning that
LETONE high-pressure rubber hose also has excellent high-pressure performance. Compared with the SAE standard, its pressure exceeds the SAE standard by 36%, which allows the hose to maintain stable performance when facing high pressure and ensure the normal transmission of hydraulic oil.
Of course, long life is also one of the distinguishing features of
LETONE high-pressure rubber hoses. Used with LETONE's exclusive integrated hose connectors and hydrogenated nitrile seals, this hose has a warranty life of up to two years. This means that under normal use conditions, users can use this hose with confidence without frequent replacement, thus reducing maintenance costs and time investment.
To sum up, LETONE high-pressure rubber hose has become an ideal choice for large construction machinery such as excavators and harsh environments due to its excellent performance and wide range of applications. The careful selection of inner rubber layer materials, the diversification and high pulse frequency of the reinforcement layer, the upgrade of appearance materials, and the wide operating temperature range, low bending radius and high pressure performance, long life and other characteristics make LETONE high-pressure rubber hoses popular in the market. It stands out in the market and brings users a more efficient, stable and reliable hydraulic oil transmission experience.
