Power Steering Lines


Eaton is a specialist in Power Assisted Steering Acoustics optimization. We have a long track record as provider of high quality power steering lines with customizable steering feel combined with a special expertise and multiple patents in raising acoustic performance.

While steering assistance on passenger cars is more and more taken over by electric systems, commercial vehicles will continue to rely on hydraulic solutions as hydraulic assisted power steering offers higher performance at less space required.

Eaton’s power steering hose offerings provide a solution for every need. Common applications include:

  • Passengers Vehicles
  • Light Commercial Vehicles
  • Medium Duty Commercial Vehicles
  • Heavy Duty Commercial Vehicles
  • Harvesters
  • Agriculture Tractors
  • Forge Lifts
  • Wheel Loaders

Addresses these engineering challenges:

  • Reduce unwanted noise and vibrations generated from the oil pump in a hydraulic power steering system
  • Improve the “steering feel” of heavy duty hydraulic vehicles

Product Features

  • Reduced assembly time
  • Quick connector fittings
  • Zero-leak performance
  • Individual, customized solutions made of plastic or corrosion-resistant metal
  • Tool-free handling even in narrow spaces

FC510-08 Hose
Commonly used for power steering pressure lines (pump outlet to steering gear inlet), the FC510-08 power steering hose provides superior temperature range for extended performance (-40°F to +300°F/-40°C to +150°C), a 2-wire braid operating performance, reduced bend radius and worldwide fitting selection and availability.

1H103 Hose
The 1H103 is a heavy duty, power steering return, providing superior temperature range (-400°C to 1500°C), extended hose service life, reduced warranty costs, easier routing and installation with 6 through 18.6mm sizes available.

EC004 Hose
The EC004 is the most “asked for” power steering return line for heavy duty truck, providing superior temperature range (-51°C to 150°C /-60°F to 302°F), Eaton’s 3 year warranty and excellent kink resistance. The EC004 power steering hose line is also impulse pressure tested and ozone resistant.
