New High-Performance Aeroquip Hose Boosts Reliability, Lasts Longer

Aug. 16, 2022 - Danfoss Power Solutions has launched its Aeroquip by Danfoss EC881 Dynamax hose.

The two-wire braided hose offers higher reliability and extended service life, reducing maintenance time, costs, and waste, said Danfoss.

EC881 hose outperforms standard EN 857 type 25C hose specifications with a 35% higher pressure rating, 26% higher operating temperature, eight times the abrasion resistance, 67% greater flexibility (1/3 SAE bend radius), and five times the impulse life (1 million qualified impulse cycles).

Those benefits come from 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,” said Scott Bauman, product manager, rubber hydraulic hose and fittings, Danfoss Power Solutions. “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.”

Higher pressure capabilities let the EC881 hose replace heavy, rigid four-wire spiral hose in some 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 also weighs less than spiral hose. That reduces a machine’s overall weight, which improves fuel efficiency.

Aeroquip by Danfoss EC881 Dynamax hose is available in -4 through -24 sizes (0.25” to 1.5” inner diameter). It 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 equipment.
