The gasket may include an upper portion arranged for positioning on the top surface of the cylinder and for making a seal with the top surface, and a lower portion extending downwardly from the upper portion and around the side surface of the neck of the cylinder, such that the lower portion is arranged to make a seal with the side surface of the gas cylinder. Face and gland seals may be established by the gasket with an opening that receives the gasket and an associated cylinder neck.
