A receiver/dryer includes a canister with a cylindrical sidewall, an integral lower end, and an open upper end. A pick-up tube is disposed centrally within the canister. The lower end of the pick-up tube has a wedged-shape and is supported by the lower end of the canister. The upper end of the pick-up tube has an annular groove that carries an O-ring seal. A lower baffle and lower filter pad are received over the pick-up tube with the lower baffle having a tight slip-fit therewith. Loose desiccant is supported by the lower baffle and filter pad. An upper filter pad and upper baffle are received over the pick-up tube, with the upper baffle having a slip-fit therewith. An upper end cap is secured to the open end of the canister, with the pick-up tube being received within an outlet passage in the upper end cap, and the O-ring seal providing a fluid-tight seal between the pick-up tube and the end cap. According to another aspect, a desiccant tube is disposed in fluid-tight relation around the pick-up tube and extends between the lower baffle and the upper baffle. The lower baffle has a fluid-tight fit with the desiccant tube, and preferably has an annular bead and annular flange on the desiccant tube retaining the baffle to the tube. The pick-up tube can be connected off-center to the end cap, and then bent or curved so as to be aligned with the desiccant tube.
