Don't go camping without this great bundle from Flame King! The Flame King 5LB bundle comes with a 5LB refillable propane tank and a propane rubber hose YSN-QCC-1LB. The Flame King 5LB Propane Tank is a pre-purged vacuum ready for the filling of propane avoiding the cost and headache of purging your new tank. It is built from high-grade welded steel and powder-coated for rust prevention. For your safety, your tank comes with an OPD valve to prevent overfilling. It is also x-ray and hydrostatic tested. You can be sure to transport safely both in the US and CA as they are DOT and Transport Canada certified. Flame King's 4-FT propane adapter hose (YSN-QCC-1LB) connects your 1LB appliance to a 5LB propane tank using a QCC1 or Type-1 connection. The hose tethers to the CGA hook on your propane-powered appliances including camping stoves, tabletop grills, lanterns, and more.
