Product Details

The OTC Tools 71789 is a replacement high and low side hose set designed for use with compatible Robinair A/C service machines. Sold without couplers, this color-coded hose pair delivers reliable, leak-resistant performance during automotive refrigerant recovery and recharge service operations.

The set includes two individual hoses: the OTC70020 low side hose (blue) and the OTC70021 high side hose (red). Each hose measures 9 feet (108 inches) in length. The high-side hose is constructed from reinforced rubber with brass connectors at each end, while the low-side hose features reinforced nylon with a brass connector on one end and a quick-connect fitting on the other. O-rings are included with the fittings.

These hoses are engineered for a working pressure range of 0 to 500 PSI and are compatible with R-134a refrigerant. They are direct replacements for Robinair A/C service units including the 34788NI, 34788NI-H, 34288NI, and 34988NI models.

Key Features:

  • Includes both OTC70020 (blue, low side) and OTC70021 (red, high side) hoses
