We describe the design and operation of the fluid delivery, monitor and control systems for the SLD barrel Cherenkov Ring Imaging Detector (CRID). The systems deliver drift gas (C<inf>2</inf>H<inf>6</inf>+TMAE), radiator gas (C<inf>5</inf>F<inf>12</inf>+N<inf>2</inf>) and radiator liquid (C<inf>6</inf>F<inf>14</inf>). Measured critical quantities such as electron lifetime in the drift gas and ultra-violet (UV) transparencies of the radiator fluids, together with the operational experience, are also reported. © 1993 IEEE
