Established in 1994, Hebei Qianli Rubber Products Co., Ltd. has grown up into a leading hydraulic hose manufacturer in China. With the continuous economic development, hydraulic hoses have been extensively used in industries, mines, steel works and chemical factories. Compared to rigid pipes, hydraulic rubber hose can bend to specified radius and resist vibration damage.
Our factory has introduced advanced hose making machinery and production process to improve hose quality and satisfy customer's stringent requirements. In recent years, we've exported to many countries including America, Britain, France, German, East Asia and other countries.

READ MOREHydraulic Hose FAQs for your better knowledge
A: Many users are often confused by this problem. As a result of high tensile steel wire, single wire braided hydraulic hose is workable to support specified working pressure. For this reason, it is not necessary to employ double wire braid hose. However, when the working environments are abrasive and corrosive, two braided hydraulic hose is a better alternative. The extra braid protects interior rubber and greatly extends hose service life.
A: SAE J517 hydraulic hose standard serves as the most popular benchmark today. Most manufactures have taken it as a production guideline. However, not all hydraulic hoses are strictly produced according to J517. In most cases, our hydraulic hoses are produced depending on our customers' specified applications.
Wire reinforcement of hydraulic hose have two main types - braided and spiral. Medium or high pressure hoses usually features single- and double-wire braided construction. Wire braided hoses are usually applied to heavy-duty trucks, construction equipment. Its main advantage is great flexibility.
Spiral wire hoses - four or six, provide super high pressure, excellent kick resistance and high abrasion resistance. These hoses are used in more powerful equipment and earth movers.
