Abstract: Systems and methods are disclosed that include providing a tubing construction with at least one layer formed from a thermoplastic vulcanizate (TPV). The tubing construction is suitable for use in pump applications subjected to cyclic loading and unloading. The tubing construction maintains a flowrate stability of +/−10% for an extended period of time to provide consistent fluid dispensing and/or dosing for an extended life of the tubing construction and/or the fluid pump.

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.
