CO2 Stem, 1/4" MPT (Left Hand Thread)

This CO2 Connection Stem works with all left hand thread CO2 regulators. Use this stem in conjunction with the Connection Nut to attach your regulator to the CO2 tank. NOTE: our most recent shipment of these connection stems did NOT come with a rubber washer. We're not sure if this is a pattern from our supplier or not, but for now you can use these connection stems along with a standard nylon CO2 washer to make a leak-free connection.
