Abstract
A self-sealing fill nipple for a pressure regulator having a fill port, includes a body having a first end having a quick connect fitting, a mid-body region and a threaded region for threadedly engaging the pressure regulator at the fill port. The threaded region extends from about an end of the body toward the mid-body region and is spaced therefrom by a gap. The threaded region has crest and root diameters. The mid-body region includes a tightening element proximal the quick connect fitting and a gap between the tightening element and the threaded region. The gap has a diameter equal to or less than the threaded region root diameter. A combination of a pressure regulator and a self-sealing fill nipple are also disclosed.
