Abstract: Systems and methods are disclosed that include providing a multilayer tubing construction with an inner layer, an intermediate layer, and an outer or third layer formed from a material comprising a non-phthalate plasticizer, such as TOTM, DOA, DOTP, or combinations thereof. The multilayer tubing may be suitable for carrying a fuel, or other flammable substances therethrough, and resists delamination between layers when exposed to high humidity climates.
