Robinair Premium Refrigerant Charging Hoses are built for long life and dependability. A strong, six-sided crimp provides a reliable connection between the hose and the barb, even at maximum pressure. The coupler nuts are deeply knurled for quick finger-tightening. Enviro-Guard Hose jackets are ideal for High Pressure refrigerants with a working pressure of 700 PSI and a burst pressure of 3700 PSI.
