Factors to Consider When Choosing Your Hydraulic Pe Fitting

When deciding on which type of pe fitting to select for your system, there a few important factors to consider. These include the following:

working pressure
fitting configuration
desired attachment
size of piping
material of the conductor or component you are connecting to
pricing requirements
Equally as important is the use of a seal. The fluid power industry is slowly converting to elastomeric seals to help prevent leakage. However, depending on your application, you must ensure that your seal is compatible with the type of hydraulic fluid flowing through your system. Very few applications will require anything other than Buna Nitrile or Viton.

The majority of fitting types are available in different materials including the following:

stainless steel
specialty materials
Base your material selection on the fluid flowing through your hydraulic system as well as ambient conditions. Depending on what you need for your application, each material will have different performance characteristics. Often times, the first obstacle to tackle is matching your fitting to a similar material to the conductor or component that you will connect it to.

Another important component is choosing the geometry of your fitting. Generally, the geometry fitting is the alphabet letter the fitting resembles. There are fittings that can change the direction of flow and various increments (45° or 90° elbows [L]), or a swivel that allows two jointed sections the ability to rotate. You can also find fittings that have the capability to split or combine flows with the following:

run or branch tees (T)
“wahys” (Y)
