Airserco has been a leading single source provider of refrigerant processing equipment and accessories over the last seventy years. Airserco`s refrigerant indicator with pressure gauge is used between the cylinder valve and the charging hose in place of the usual cylinder adapter. It can be used either with older series of cylinder band heaters or independently. The 4560 liquid eye refrigerant indicator has a liquid eye to show the liquid or vapor phase of refrigerant flow, and a 1/4" flared-end ball valve.
