DIN EN856 4SP hydraulic hose is composed of 3 parts: tube, reinforcement, and cover. The tube is made from a black oil-resistant synthetic rubber material, making the hose have excellent performance in delivering hydraulic oil. Reinforcement is made from four layers of high tensile steel wire spiral, making hose suitable for ultra high-pressure applications. And the high tensile reinforcement makes the hose have a solid structure and is resistant to bend, kink & fatigue. The cover is made of abrasion resistant synthetic rubber. BAILI hose factory made innovations on the spiral hydraulic hoses recently. 1) We can produce the spiral hose with smooth cover which can offer more alternatives to customers. The smooth spiral hose with high flexibility, high pressure and high impulse. 2) The spiral hoses with steel mandrel will not limit by the short length and the maximum length we can produce is 100m per roll. 3) The wrapped cover 4SP hydraulic hoses, we adopted with narrow nylon tape which makes the surface of wrapped cover more compact and good-looking. And this change will enhance the adhesive force between the outer cover and steel wire reinforcement.

Very high pressure applications used for petroleum-based hydraulic fluids.

 The type EN856 4SP Hydraulic system service with petroleum and water-base fluids, also can be used in other various industries.

About hose temperature:

Hydraulic hoses are exposed to two temperature concerns which include internal liquid temperature and external working temperature. Performance in terms of both temperatures determines the rating for hoses, with a maximum and minimum functioning temperature rating. If you exceed these ratings, this can result in severely reduced working life or even failure. This is why it is pertinent to use a hose what a proper rating to both the liquid temperature and the environment temperature.
