Abstract
A cylinder valve outlet includes a bore with a large cylindrical entry leading to a tapered seat. A nipple with a cylindrical neck is fit into the large diameter entry of the bore of the valve outlet. The nipple further includes an arcuately convex mating end for seating in the conically tapered seat of the valve outlet. A seal enhancer is between the valve outlet and the nipple. The seal enhancer is generally tubular with opposed leading and trailing ends and a cylindrical section therebetween. The leading end is tapered for engagement between the tapered seat of the valve outlet and the mating end of the nipple. The trailing end of the seal enhancer is flared outwardly. The seal enhancer is shorter than the mating portions of the nipple so that the outwardly flared trailing end is visually readily apparent. The outwardly flared trailing end also facilitates separation of the seal enhancer from either the nipple or the valve outlet when the gas cylinder is being replaced.
