Flame King YSN330 is a 30 lb steel propane cylinder with an integrated gauge and OPD valve made for safe, long-lasting fuel supply for grills, camping, and outdoor appliances.

This heavy-duty white propane tank is built from welded, powder-coated steel and arrives pre-purged and vacuum-ready for filling.

DOT and Transport Canada certified with X-ray and hydrostatic testing, the YSN330 is designed for regulated, dependable transport and use in the U.S. and Canada.

Will this tank fit my grill, RV, or outdoor heater?
