How to Choose Your Hydraulic Fitting

- Jan 23, 2018 -

When deciding on which type of fitting to select for your system, there a few important factors to consider including your working pressure, vibration, fitting configuration, desired attachment, size of piping, flow, material of the conductor or component you are connecting to and 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, but depending on your application, you must be sure 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 plastic, brass, copper, steel, stainless steel or specialty materials. Your material selection should be based on the fluid flowing through your hydraulic system as well as ambient conditions. Depending on what is needed 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 is being connected to.

Another important component is choosing the geometry of your fitting. Generally, the geometry fitting is described by 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. Fittings can also be found that have the capability to split or combine flows with run or branch tees (T), “wahys” (Y) and crosses (+).
