High Pressure Hydraulic Rubber Hose with Fittings – China Suppliers and Factory Quality Assurance
Hydraulic rubber hose is a type of rubber hose which superior to ordinary rubber hose whatever in performance or in function. It is mainly spiral by inner rubber layer and middle rubber layer and several coils of steel wire. The inner rubber’s function is to allow the conveyed medium to withstand a certain pressure and meanwhile to prevent the steel wire be corroded. The outer rubber layer is to prevent the steel wire from receiving other types of damage. That makes steel wire as framework material plays a certain role in reinforcement. Hydraulic rubber hose not only can use hydraulic power to transport media such as water and air, but also transmit high-pressure media such as oil, so that it can ensure the continuous circulation of liquid and energy transfer.
Hydraulic rubber hose according to its production process mainly divided into two type: Wire braided hydraulic hose and Spiral wire hydraulic hose.
Hydraulic rubber hose mainly used for mine hydraulic support and oilfield development, also suitable for engineering construction, lifting, transportation, metallurgy forging press, mining equipment, vessels, injection molding machinery, agricultural machinery, various machine tools and industrial departments.
Applications: carry hydraulic liquids such as: petroleum based (such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) and water based liquids (such as emulsion, oil-water emulsion, water) ,etc.

Frequently Asked Questions (FAQ)
Hydraulic rubber hoses are primarily categorized into two types based on their production process: Wire Braided Hydraulic Hoses and Spiral Wire Hydraulic Hoses.
It consists of an inner rubber layer (to withstand pressure and prevent wire corrosion), a middle rubber layer, several coils of steel wire (acting as reinforcement framework), and an outer rubber layer (to protect against external damage).
They are widely used in mine hydraulic supports, oilfield development, engineering construction, lifting, transportation, metallurgy forging press, mining equipment, vessels, injection molding machinery, and agricultural machinery.
They are designed to transport water, air, and high-pressure petroleum-based liquids (mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) as well as water-based liquids (emulsions, water).
Our hoses conform to international and national standards including DIN EN 853, DIN EN 856, SAE J517, GB/T 3683-2011, GB/T 10544-2003, ISO1436, and ISO3862.
Wire braided hoses operate from -40℃ to 100℃ for oil and above 80℃ for water-based liquids. Spiral wire hoses support working temperatures ranging from -40℃ to 120℃.
