Six easy steps to choosing the right hydraulic hose

Six easy steps to choosing the right hydraulic hose

The inside of fluid power machinery is complex, and subject to some of the harshest conditions on mining sites. To address this, Gates® has designed a fit-for-purpose range of industrial-grade hoses, ideal for transporting water and emulsions between hydraulic components.

The Megasys® portfolio offers increased performance and flexibility, facilitating peak plumbing and routing in compact applications.

Capable of reducing expenditure by up to 64 per cent, they are easy to install and require fewer bent tube fittings. With such diverse capabilities within the range, it’s important to select the most suitable hose for each individual system.

Understanding hose identification

The Gates® Megasys® range is separated into two main categories:

  • Wire-braid hose – M3K, M4K, M5K, M6K, MXT, MXT-XTP: These are constructed using high-tensile steel wire and are tested to 600,000 cycles.
  • Spiral-wire hose – EFG3K, EFG4k, EFG5k, G8K: These are constructed from four to six alternating layers of spiralled, high tensile steel, and are tested to up to one million impulse cycles.
  • Xpiral hose – MXG4K-XTP, MXG5K-XTP: Built with Gates patented Xpiral™ woven spiral technology, MegaSys MXG™ 4K/5K hydraulic hose is lightweight, highly flexible and qualified to one million impulse cycles. MXG™ 4K/5K exceeds the performance of wire spiral constructions, but with the lower weight and flexibility driven by Gates materials science technology.

Identification laylines are printed along the side of each product, and are used to communicate critical information about its specifications. This offers increased efficiency for purchasing or organising stock on site. In addition, hoses in the MegaSys® line are distinctly colour-coded to quickly and easily view pressure ratings.

  • YELLOW: 8,000 PSI, G8K
  • ORANGE: 6,000 PSI, EFG6K\
  • RED: 5,000 PSI, M5K/EFG5K/MXG5K-XTP
  • BLUE: 3,000 PSI, M3K/EFG3K

Alongside the respective colours, each hose description label will list the I.D number, bend radius, psi working pressure, SAE and European standards, and important features such as flame resistance.

Checklist for suitability

To makes things easy to remember, Gates® recommends using the STAMPED method for running through hose selection criteria:

S = Size
T = Temperature
A = Application
M = Material to be conveyed
P = Pressure
E = Ends or couplings
D = Delivery (volume and velocity)
