How to Choose Hydraulic Hose

Hydraulic hose is used to convey hydraulic fluid in a system. Whereas pipes and tubes tend to be rigid to accommodate tight spaces, such hoses are intended to use where flexibility is required to allow movement between two ports. One common use of hydraulic hose is in construction vehicles where external tools must be free to move. Strict standards govern specification and installation. Here are some things to know.


A hydraulic hose is usually made up of three layers. The inner tube must be compatible with the liquid it conveys, maintaining elasticity without added stress. The reinforcement layer surrounds the inner tube with a coiled wire to resist tearing. The outer layer is usually composed of rigid materials that protect the interior. Based on the material carried, the hose must be of the right construction type. Reinforced types have extra buffer in the middle layer. Coiled and corrugated hoses allow for expansion and compression without added stress. Articulated types are built in sections for easy bending and flexing.

The word “STAMPED” offers an easy acronym to properly account for the various criteria for proper selection:

  • Size – Check for the inside and outside diameters and the overall length.
  • Temperature – Verify the required temperature for a particular application and check the recommended range.
  • Application – Check the minimum radius bend needed. This is a measure of how much the hose can bend without constricting inside liquid flow.
  • Material – What is being conveyed? Is it compatible?
  • Pressure – Make note of the maximum pressure rating, accounting for pressure spikes as well.
  • Ends – Also known as couplings, the ends refer to the terminal attachments on the hose.
  • Delivery – How many hoses are needed and how often are they to be replaced?

Hydraulic hoses serve an important function in various machines, including vehicles. Careful consideration is needed for selection and replacement as these hoses are often subject to high pressures, temperatures and chemicals.
