Hydraulic hose can be made from a variety of materials depend on the app and the specific demand of the hose. Here are some common materials to produce hydraulic hose:
This is the most common material for hydraulic hoses. Besides, it is for both the inner tube and outer cover of the hose. While the most used are NBR and EPDM. NBR has the best oil and corrosion resistance among the rubbers. Thus it normally serves as the inner tube which will work together with oils. While EPDM has better wear, age and weather resistance. Thus it often serves as the cover of the hose. It will protect the hose from external impact and damage.
Some hydraulic hoses adopt such materials like nylon or PU. These hoses are light in weight and flexible. Besides, they can bear chemicals such as acid and alkali.
Almost all the hydraulic hoses has a steel wire reinforce. Some has just 1 layer, while some has 4 or even 6 layers. It is a necessary material for such hose.
Some hydraulic hoses are made from Teflon (PTFE). It is a synthetic material and famous for its excellent chemical resistance and ability to handle high temp. PTFE hydraulic hose is SAE 100 R14.
Hydraulic hoses can also absorb stainless steel. As it is a highly durable material that can handle extreme temp and pressure.
The specific materials used to make a hydraulic hose will depend on these factors. Such as the intended app, the work condition, the pressure and temp demand of the hose.
