Get it Right! A Guide to Choosing the Best Hydraulic Hose for Your Needs

Choosing the right hydraulic hose for your project is essential for efficiency, safety, and productivity. But with all of the hydraulic hoses on the market today, picking the right one can be a challenge. 

When shopping for your hydraulic hose, there is an easy to remember guideline that should lead you in the right direction. Remember STAMP: Size, Temperature, Application, Materials, and Pressure. You must check all of these boxes to find a hose that will meet your needs. 

Read on to learn how to simplify shopping for hydraulic hoses!

Size

The first thing you need to determine in choosing your correct hose is the size. Hydraulic hoses are measured by their inside diameter. Hose diameters are measured to the nearest 16th of an inch, so get out your caliper in order to get an exact measurement! 

Knowing the external diameter of the hose is important for fitting couplings and hose connectors. make sure you know the length of hose required as well.

Temperature

The next thing to be aware of when changing hydraulic hoses is the temperature of the fluid, or media temperature. All hydraulic hoses have a maximum temperature rating that typically ranges from 90 degrees Celsius to 150 degrees Celsius. This is the max temperature for the hydraulic fluid flowing through your hose. 

If the temperature is exceeded, the excess heat will start to breakdown your hose which will lead to early deterioration. 

If you plan to use your hoses in extreme ambient temperatures, or the temperature of the outside of the hose, be sure your hose is formulated to withstand such extremes.

Application 

Next, you’ll need to consider how and where your hose will be used. The hose must be able to withstand vibrations, impact, and external temperatures or weather. The hose needs to be able to stand up to the job. 

Another thing to note about hydraulic hose replacement is the bend radius. Hoses can bend only a certain amount. Exceed that amount, and the hose will kink and reduce flow, or crack and break. Make sure to buy from a reputable hose company who understand these limits. 

Media and Materials 

Another important factor is the material of your hose. Know what media will be running through your hose. If your media can degrade petroleum-based rubbers, then consider a hose that does not use this material as an inner layer. 

If you are repairing a sandblaster, make sure the outer layer of your hose can stand up to abrasion. 

Pressure

Finally, you must consider the pressure of the fluids within your hose. Adhere strictly to pressure ratings of your hose to prevent accidental bursts or breakages within your hose.

As a general rule of thumb, the smaller the diameter of the hose, the higher the pressure rating. The pressure rating equates to the maximum amount of pressure the hose can withstand. Do not exceed this!
