Abstract: A pressure indicator includes a body, a piston, first and second biasing elements, and a rotatable disc. The piston is disposed at least partially in a bore of the body at a first longitudinal axial position relative to the body when pressure of fluid acting on the base is below a threshold pressure. The first biasing element is disposed between a base of the piston and a shoulder of the body, wherein a force of the first biasing element is overcome by pressure of fluid acting on the base at or above the threshold pressure, thereby allowing the piston to move to a second longitudinal axial position. The rotatable disc has a first rotational position when the piston is in the first axial position. The second biasing element is configured to urge the disc to a second rotational position when the piston is in the second axial position.

Abstract: A boss configured for attachment to a pressure vessel includes a first bore therein and a bearing disposed at least partially within the first bore. A system for supporting a pressure vessel on a vessel mount includes a boss, a bearing, and an attachment element. The boss is attached to the pressure vessel and has a first bore therein. The bearing is disposed at least partially within the first bore and has a second bore therethrough. The attachment element is configured to be affixed to the vessel mount, wherein a portion of the attachment element extends through the second bore and is slidable within the first and second bores substantially along a longitudinal axis of the pressure vessel. A method is described for supporting a pressure vessel on a vessel mount.

Abstract: A boss includes a neck and a flange that extends radially outward from the neck. The neck includes a bore therethrough with a longitudinal axis. The flange includes an exterior surface, an interior surface, and a peripheral surface at a farthest extent from the longitudinal axis. The peripheral surface connects the interior surface and the exterior surface and includes, along any radius of the boss, a first circumferential ridge and a second circumferential ridge, wherein the first circumferential ridge is located closer to the exterior surface than the second circumferential ridge. In another aspect, a pressure vessel includes a boss and a liner. In yet another aspect, a method of assembling a pressure vessel is described, which includes inserting the boss through the aperture of the liner and connecting the boss and liner so that the peripheral surface of the boss mates with the perimeter surface of the liner.
