The Gaslow Propane to 21.8LH Adapter 01-4331 is used to convert a POL propane Pigtail hose or a 37mbar regulator to fit a Gaslow refillable gas cylinder. This adapter can also be used to convert a propane POL regulator hose to 21.8LH which will then take all of the continental adapters for using the countries own cylinder fittings.
