The Flame King 100LB Multi-Valve Propane Tank is a must-have if you don't want your tank to be transported every time you need it refilled! This allows you to do on-site refilling of your propane gas without disconnecting your appliances. It includes a service valve, a high-capacity filler valve with integral back-check, a pressure relief valve (375 PSIG), and a POL valve, all in one single unit. This tank is also pre-purged and vacuum-ready for the filling of propane avoiding the cost and headache of purging your new tank. 100LB propane tanks are great for mixed heating systems, home fireplaces, dryers, grills, food trucks, catering services, and many more. It is built from high-grade welded steel and powder-coated for rust prevention and long-lasting exterior protection. It is x-ray and hydrostatic tested. Transporting this tank anywhere in the US and CA is very safe, as it is DOT and Transport Canada certified.
