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 barb, even at maximum pressure. The coupler nuts are deeply knurled for quick finger-tightening. Enviro-Guard hoses are ideal for high pressure applications, including R-410a systems.

Enviro-Guard automotive A/C service hoses feature a special barrier material that prevents virtually any permeation of refrigerant yet still remains flexible. Red 240" Enviro-Guard Hose for Automotive R-134A.
