• the second fitting sleeve including
• a locating segment formed on a first end thereof and having male threads,
• a threaded hole defined on a second end of the second fitting sleeve opposite the locating segment, and
• a passage extending inside the first end of the second fitting sleeve, wherein a diameter of the passage is less than a diameter of the threaded hole, the second fitting sleeve further including
• a first stepped shoulder defined between the threaded hole and the passage,
• a second stepped shoulder extending away from the first stepped shoulder,
• a stop shoulder extending away from the second stepped shoulder and having an aperture,
• wherein the passage has a valve seat thereon,
• a second opening formed on a distal end of the valve seat,
