Dura-Pulse® Inner tube technologyA fluid conveyance revolution from the inside out

Aeroquip® Hydraulic Hose

The power of Dura-Pulse® technology relies on a unique blend of polymers and reactive chemistry to achieve enhanced material properties. This brand new formulation of NBR (acrylonitrile butadiene rubber) features both the superior heat stability of peroxide-cured rubber and the outstanding flexibility of sulfur-cured rubber.

What is Dura-Pulse® Technology?

Dura-Pulse® is a patented inner tube technology that allows hoses to be more durable, flexible, and cost-efficient.

As the experts in fluid conveyance, we challenged ourselves to develop a brand new inner tube starting at the molecular level. The result is a technology that enables new opportunities for our customers and shows how our connections move the world.

Excellence under pressureBoth spiral and two-wire braided hoses created with Dura-Pulse® technology exhibit superior pressure and heat resistance. The Aeroquip® EC600 X-Flex® spiral hose uses Dura-Pulse® technology to offer operating pressures up to 420 bar and temperatures up to 121°C, while the Aeroquip® Dynamax® EC881 two-wire braid hose handles pressures up to 450 bar and max temperatures of 126°C.

Take the easy routeHoses with Dura-Pulse® inner tubing are more flexible than others in their class, boasting a superior 1/3 SAE bend radius for EC881 hoses. Engineers requiring the higher operating pressures that spiral hoses traditionally deliver often had to sacrifice flexibility. Now, our lighter-weight EC881 two-wire braided hose provides the flexibility needed for more direct routing while offering operating pressures up to 450 bar, making installs faster, easier, and more cost-efficient. In addition, overall machine weight is reduced for improved fuel efficiency.

Run longerHoses used in demanding applications often degrade because of high pressure spikes and impulses that are continually being applied to the hose. Hoses with Dura-Pulse® technology have up to 5x longer life than SAE/EN standards and support up to 1 million impulse cycles to ensure equipment performs reliably even in the harshest environments. With Dura-Pulse® technology, operators can reduce maintenance downtime and the possibility of hose failure. Plus, by combining hoses made with Dura-Pulse® inner tubing and our high-performance hose fittings, operators can achieve an even longer, leak-free hose assembly life.
