5 Considerations for Hydraulic Hose Replacement #2 Temperature - LowTempHose-GRO

In our last blog post in this series, 5 Considerations for Hydraulic Hose I No.1 Size, we talked about determining the correct size (inside diameter) of your hose and the importance flow velocity makes to the proper efficiency of your hydraulic system. The next step in our suggested S.T.A.M.P. method is Temperature.

Temperature has an enormous effect on the service life of a hose. To get the maximum service life, there are two temperature considerations to identify, the external environment and the conveyed media.

Evaluate the application your replacement hose will be operating in. What’s the ambient temperature or the temperature that exists outside the hose? Where is it being used? Maybe your application is mining equipment in the desert with extremely high temperatures or conversely, a cold storage application where temperatures can reach as low as -70°F. Both are brutal operating conditions with ambient temperatures that can have damaging adverse effects to the hose cover.

Once you’ve identified the ambient temperature, your next consideration is media temperature. What’s flowing through the hose and at what temperature? Is it a lubricating oil, water, petroleum-based fluid or air? Keep in mind that one media type (for example air) may be rated at a different temperature than another (for example water) for the same hose.

Let’s consider an engine compartment; the fluid flowing inside the hose may actually be lower than the ambient temperature of the environment. You’ll want to select a hose that has a working temperature equal to or greater than both the fluid and ambient temperatures.  The Parker Hose Products catalog 4400 Technical Section provides a temperature chart to help determine the correct Parker hose based on the external environment and conveyed media.

In addition to the Parker Hose Products catalog, your local ParkerStore is a great resource for evaluating your application and determining the best hose for your needs.

The next blog post in our series will be the third step of the S.T.A.M.P. method: Application. If you'd like to see all five steps in details, check out our ParkerStore S.T.A.M.P. video on our website.
