New Yellow Jacket® high-pressure control hose for HFC, HCFC, and CFC refrigerants has a thermoplastic polymer inner tube and cover that eliminates the vibration failure problems that are present in copper capillary tube installations, claims the company. According to the manufacturer, the higher temperature ratings of this thermoplastic polymer to 266 degrees F eliminate the failures caused by maximum load conditions on rubber-type oil pressure control hoses. The company states that between the inner tube and the cover, the hose is reinforced with polyester braid of high tensile strength with high modulus, giving it the ability to withstand higher pressures.
