For ultimate conveyance of motor fluid, truck owners need to use the right tubing. Hydraulic hoses are flexible tubes that are designed to transport hydraulic fluids from one hydraulic component to another. These hoses are typically consist of three parts — (1) an inner tube that conveys the fluid; (2) a layer of spiral wound wire, braided wire, wire helix, textile yarn or other types of reinforcements; and (3) an outer layer to provide protection against physical damage caused by abrasive elements, harsh weather, et cetera, et cetera. The hydraulic hoses used in trucks are typically made of flexible material, such as rubber or elastomers. To keep trucks running efficiently on the road, it is critical to maintain a leak-free hydraulic system. But as expected, leakage can always occur when hydraulic hoses are being used to make hydraulic connections. 

Let's discuss some of the things that can be done to leak-proof hydraulic hoses used for transporting fluid in trucks. 

Correct assembly

The first and most significant step when it comes to leak-proofing hydraulic hoses is to ensure that they are properly fitted. For instance, the hose end of hydraulic couplings must be mated with hoses that match the size and type of hoses recommended for the couplings. This way, the hoses can fit tightly and prevent potential leakage. Proper assembly also requires that hydraulic hoses be inserted all the way in the hydraulic fitting because loosely fitted hoses can easily get disconnected due to fluid pressure. To make out the insertion depth of the hose fitting, the distance from the shell of the fitting to the bottom end of the fitting. Mark a line indicating the hose insertion depth on the hose cover and push the hose into the fitting until the tip of the fitting is level with the line. The line acts as a visual check to see if the hose has been completely inserted in the fitting.

Correct use

Not all hydraulic hoses are created equal. For that reason, it is important for truck operators to choose hydraulic hoses that are suited for their applications, and that they should operate the hoses within their maximum temperature and pressure ratings.

While steps can be taken to prevent leakage of truck hydraulic hoses, the hoses can still leak due to a myriad of factors. If you happen to encounter leaking problems with the hydraulic hoses in your truck, call for professional assistance immediately.
