Abstract:
A system for providing fluid communication to a quartz tank used in a semiconductor device fabrication process, the system comprising:a quartz pipe extending from the quartz tank, the quartz pipe including an externally threaded fitting;a synthetic resin tube having an internally threaded fitting on one end thereof that is compatible with the externally threaded fitting on the quartz pipe; anda quick-connect fitting providing fluid communication between the quartz pipe and the synthetic resin tube, the quick-connect fitting comprising:a first coupling member having a proximal end and a distal end, the first coupling member including a pipe receiving section threadably engaged with the externally threaded fitting of the quartz pipe, and a ramp support section with at least one spiral ramp formed therearound;a second coupling member having a proximal end and a distal end, the second coupling member including a sealing member at the proximal end thereof that is engaged with the distal end of the first coupling member, and an extension portion protruding away from the sealing member that is threadably engaged with the internally threaded fitting of the synthetic resin tube; anda locking collar movably engaged with the second coupling member and having at least one lock member disposed on an interior surface of the collar that is slidably engaged with the at least one spiral ramp of the first coupling member.
