Propane Outlet Lines (P.O.L.) hoses serve the critical function of safely transporting propane gas from the storage tank to a regulator. These hoses are specifically designed for durability and flexibility to withstand the pressures of propane gas and the rigors of travel. The P.O.L. fitting screws into the internal threads of a propane tank valve using a left-hand threading and relies on a O-ring that presses against the tank valve, creating a gas-tight seal.
