A connector system configured to couple a first tubular member to a second tubular member includes a body, an outer sleeve positioned circumferentially about the body, and an actuator assembly positioned within an annular space defined between the body and the outer sleeve. The actuator assembly includes one or more piston rods, a primary piston ring coupled to respective first ends of the one or more piston rods, and an actuator ring coupled to respective second ends of the one or more piston rods, wherein the actuator assembly is configured to move axially within the annular space to drive multiple collet segments from an unlocked position in which the multiple collet segments do not engage the first tubular member and a locked position in which the multiple collet segments engage the first tubular member.
