Hydraulic Swivel Seals

Posted on Friday, March 15, 2013 in UEA Blog


A hydraulic swivel is a rotary manifold that allows one to transmit fluid power from a stationary point to an object that moves in a rotational fashion. Seals are a crucial part of a hydraulic swivel, and United Equipment Accessories takes seals seriously. A seal is a component that contains pressure and excludes contamination. Seals are of the utmost importance within the fluid power industry.

A standard UEA swivel consists of numerous types of seals. While each application will dictate a specific set of seals, our standard mix of seals includes:

• dust seal (v-ring or O-ring type seal)

• excluder seal (single lip outward facing shaft seal)

• thrust washer and wear ring

• inward facing uni-directional seal with integrated energizer

• high pressure cap seal with square cut energizer

One could expound for an excruciatingly long amount of time on the advantages and disadvantages of each type of seal. This current mix of seals has been developed over a period of time and has been found to work extremely well with hydraulic swivels that are found in the construction and related industries.
