Mobile and industrial hydraulics supplier Danfoss Power Solutions, Nordborg, Denmark, has launched its Aeroquip by Danfoss EC881 Dynamax hose. This two-wire braided hose reportedly offers higher reliability and extended service life versus similar products, reducing maintenance time, costs, and waste.
EC881 hose is said to outperform standard EN 857 type 2SC hose specifications with a 35% higher pressure rating, 26% higher operating temperature, eight times more abrasion resistance, 67% greater flexibility (⅓ SAE bend radius), and five times more impulse life (1 million qualified impulse cycles). These benefits are enabled by Danfoss’ patented Dura-Pulse inner tube technology, patented hybrid wire braid reinforcement, and Dura-Tuff cover.
“A hose’s working pressure, flexibility, and lifetime are key selection criteria for original equipment manufacturers. But any improvement in one factor typically weakens another factor. With our EC881 hose, we’ve optimized the tube, reinforcement, and cover layers to deliver the highest across-the-board ratings among EN 857 type 2SC hoses. OEMs no longer need to compromise — they can have the hose with the best pressure, bend radius, and impulse cycle performance,” said Scott Bauman, product manager, rubber hydraulic hose and fittings, Danfoss Power Solutions.
With its higher pressure capabilities, EC881 hose can replace heavy, rigid four-wire spiral hose in certain applications, providing a direct cost savings of up to 30% as well as several design benefits. Braided hose is much more flexible than spiral hose, which may enable OEMs to reroute and reduce hose assembly lengths, contributing to further cost savings. Braided hose is also lighter in weight than spiral hose, which reduces the overall weight of the machine, improving fuel efficiency.
Aeroquip by Danfoss EC881 Dynamax hose is available in -4 through -24 sizes (0.25 to 1.5-in. inner diameter) with pressure ratings up to 450 bar (6,525 psi). The hose is ideal for a variety of applications, including compact construction equipment, agricultural equipment, forestry equipment, mining, oil and gas, refuse trucks, aerial lifts, and railway.
