Abstract
A seal assembly includes a packing nut and a pressure ring configured to be coupled to the packing nut. An inner surface of the pressure ring defines a first circumferential groove that is configured to receive a first seal. The first seal is configured to be inserted into the first circumferential groove before the packing nut is coupled to the pressure ring such that the first seal is inserted into the first circumferential groove without being substantially flexed.
