How do you choose the correct hydraulic hose?

In various industries, there’s an abundance of kinds of hoses each of which is utilized for various reasons. There’s nothing such in the sense of “the best hose”, just a hose that is able to perform its task and do the job right. We at SS FLEXHose have possibly every needed hose you need to complete your task in efficiently. With the array of hose choices available, you may be contemplating which one to choose for their particular application. This article will cover some of the aspects to take into consideration when choosing the right hydraulic hose.

The “STAMP” Acronym

“STAMP” is the “STAMP” acronym is used to remind you of the most important attributes of hoses to be considered when choosing the right suitable hose. This acronym is a reference to the acronyms Size, Temperature, Material and Pressure. Sometimes, the term “STAMPED” is used. The letters in the last two letters are for Environmental aspects as well as “D” stands for Deliver livery.


In order to achieve the correct flow speed and flow rate, the hose I.D. must be accurately sized. The flow which is slow will result in slow system performance, whereas the flow that is too high could result in excessive pressure drops as well as system damage and leaks.

A measurement system known as Dash Numbers or Dash Sizes is utilized by the industry of fluid power to determine hose and fitting dimensions. Dash Number is the measurement of the hose’s inner diameter (I.D.) in 16ths of an inch.

Examine the layline to determine the hose’s size. If the original print has faded the original hose should be cut, and the inside diameter determined. Be sure to determine the overall length and fitting’s direction prior to cutting the hose.


Media temperature refers to the media being transported by the hose. While the ambient temperature corresponds to temperatures that surrounds the hose that is used. Both temperatures should be taken into consideration when choosing the appropriate hose. It is essential to ensure you are sure that the rating for the hose that you are looking at is equal to or greater than the highest of the ambient or media temperature of the application.

In addition, the media type with temperature of the media must be taken into consideration as different fluids may alter the effects that temperature exerts on the hose. This is the reason SS FLEXHose offers different temperatures for various fluids. It is important to confirm the specifications of the hose for temperatures and ratings.


Before deciding on a hose, it is crucial to think about what the hose assembly is going to be utilized. These questions could aid:

What kind of apparatus is the hose will be used on?

What environmental conditions are the hose exposed to?

Are mechanical forces applied to the structure?

Can the routing be restricted?

Do you need for field-attachable fittings?

Are the assemblies subject to scratches?


The hose you choose to purchase should match the product that is being transferred. The compatibility must not only cover the tube’s inner lining as well as the cover, fittings for hoses and O-rings, too.


It is essential to know the working pressure of the system and any surge pressures as well as spikes. Choose a hose for hydraulics that has the stated maximum working pressure at or above the maximum pressure of the system, and also the surge or peak transient pressures within the system.

When deciding on the parts of a hose assembly it is the “weakest link” of the assembly has to be considered. A hose is tested at the highest working pressure of the component that has the lowest rating for pressure.

Certain applications typically require particular hoses. For example, situations where hoses have to deal with the abrasive or rubbing surfaces will need SS FLEXHose’s abrasion resistant hoses with strong covers. Get in touch with SS FLEXHose with the link below for more details!
