Abstract: A remote regulator adjustment tool that can be used to adjust an output pressure of a remote regulator. The remote regulator adjustment tool comprises a housing defining a first bore extending therethrough, an adjustor piston movably disposed within the first bore, and an adjustment knob attached to the adjustor piston.

Abstract: A pressure regulator comprising a housing formed to include a bore therein, a piston moveably disposed within the bore wherein that piston comprises a first annular lip adjacent a first end, a spring disposed within said bore and comprising a first end and a second end, an adjustment cap moveably disposed in the bore, wherein the first end of the spring is in physical contact with the first annular lip and the second end of the spring is in physical contact with the adjustment cap.

Abstract: A multi-stage fluid pressure regulator, including a first stage valve arranged to open and close a fluid flow path to control flow of fluid through the valve, a first stage piston arranged for movement to open and close the first stage valve, the piston having an inner side and an outer side, a gas delivery conduit having a proximal end attached to the first stage piston and a distal end extending away from the first stage piston, the gas delivery conduit having a passage in fluid communication with the inner side of the first stage piston, and a second stage valve in fluid communication with the gas delivery conduit, the second stage valve including a second valve chamber into which the distal end of the gas delivery conduit is positioned.

Abstract: A cap and gasket for a compressed gas cylinder arranged to operate with a gas cylinder having a neck with a top surface around a gas outlet and a side surface extending downwardly from the top surface. The cap may define an inner space to house the gasket and may be attached to the gas cylinder neck. The cap may restrain gasket movement, and define a volume in which the gasket can deform, when making a seal as a piercing element enters the inner space to contact the gas outlet.
