An upper portion of the valve body defines a collar selectively formable between a first installation inner diameter to a second retention inner diameter. A service valve sealing cap includes a base portion and a generally annular sealing portion. An annular shoulder is formed on the sealing portion inner diameter, such that the radially inner diameter of the shoulder portion is less than the collar first outer diameter, and is greater than the collar second outer diameter.
