Abstract: A swivel connector for a spray gun includes a first portion, the first portion including a first interior passage that extends entirely through the first portion along a longitudinal axis and a second a second interior passage that extends along a first axis perpendicular to the longitudinal axis. The swivel connector also includes a second portion coupled to the first portion, the second portion including a third interior passage that extends entirely through the second portion along the longitudinal axis, and a fourth interior passage that extends along a second axis perpendicular to the longitudinal axis. The swivel connector also includes a connector pin coupled to both the first portion and the second portion, wherein the connector pin includes a fifth interior passage that extends along the longitudinal axis.

Abstract: A fluid housing for a spray gun. The fluid housing includes a body, a pair of inlet passages formed in the body, a pair of side ports formed through the housing body, and a side seal cartridge removably coupled to each side port. Each side port is in fluid communication with a respective inlet passage. Each side seal cartridge includes an internal passage formed therein and a plurality of openings extending from the internal passage at an offset angle. Each side seal cartridge defines a respective longitudinal axis. The fluid housing further includes a seal that is configured to be in compression along the longitudinal axis when a side seal cartridge and engages one of the side ports.
