Abstract: A hydraulic system includes a housing having a housing bore defined by a bore inner surface, wherein the bore inner surface has an internal thread formed thereon and an insert having a flange formed adjacent a first end, a sealing feature formed adjacent a second end opposite the first end, and a cylindrical outer surface extending between the first end and the second end, the cylindrical outer surface having an external buttress thread configured to mesh with the internal thread of the housing bore. The sealing feature and the flange are configured to interface with the housing to provide a fluid seal.
