Hydraulic System Informational Series - Hoses

Posted October 09 2013

Part three of the information series on hydraulic systems. Today’s topic is hose.

If the pump is the heart of the hydraulic system, the hoses are the blood vessels.  Hoses are not tricky to figure out, but it can sometimes be difficult to decide what kind of hose to get.  You’ll want to make sure that the hose you buy will comfortable tolerate both the constant pressure of fluid and the pulse force in some applications.  Agristore USA’s hoses will tolerate up to 4800 PSI of constant pressure but are not recommended for high pulse force applications. 

Another characteristic of hoses is the number of layers of wire reinforcement.  Agristore USA’s hoses are 2-wire allowing for increased PSI at the cost of some flexibility.  The 1-wire hoses are the most flexible but are generally rated at a lower PSI. 8-wire hoses can withstand intense pulse forces but are barely flexible.

The third thing to check is the temperature rating of the hose. Most hose, including Agristore USA’s, is rated for temperatures up to 100°C or 212°F. If your system is running hotter oil, make sure to get hose rated at 300°F or higher. To view our hydraulic hose listings, click here.
