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. |
