given below each drawing along with the thread designation. For
ease of measurement and identification, approximate fractional
dimensions maybe found on each drawing.
handed portion of each drawing marked "OUTLET"
represents the cylinder valve, while the right hand portion
marked "CONNECTION" represents the mating connection
