Choosing a Hydraulic Hose


Hydraulic hose users have a number of temperature, size and pressure factors to consider when choosing a hose for an application. There is a helpful acronym to track all of these considerations—STAMPED.

Size: The important sizes for a hose are inside diameter (ID), outside diameter (OD), and length.

Temperature: Most hose materials have a working temperature range.

Application: Many hydraulic hose applications involve bending, and thus hoses are rated for minimum radius bend. This rating refers to how much the hose can bend, contracting the flow space within the hose.

Material: Compatibility charts are available for hydraulic hoses, usually from the manufacturer or in third-party reference guides.

pressure: Hoses are rated for maximum system pressure. It is important that hose application intentions include pressure spikes.

Ends: “Ends” refer to the ends of a hose designed for connection, otherwise known as “couplings.” Permanent couplings are designed for attachment to a pre-determined connection. Field-attachable couplings require a user to use crimpers to seal the coupling to a connection.

Duplication (or Delivery): This guideline refers to long-term thinking about how easily a hose is replaced. A very specific or proprietary hose may be more difficult to replace than a widely available generic version. Some hoses wear out quickly due to the nature of their application, and replacement should be considered before settling on a hose type.
