Dorman 926-837 A/C Hose Assembly

Dorman 926-837 is an OE FIX A/C hose assembly for rear auxiliary air conditioning and heater systems. It replaces factory aluminum A/C lines with a flexible reinforced rubber design to simplify routing and installation under the vehicle.

  • Flexible reinforced rubber construction
  • Threaded end connections on both sides
  • High-pressure A/C system application
  • Designed for R134A refrigerant
  • Gasket or seal included
  • Fittings included
  • Molded hose assembly for underbody routing

Application Details

Compatible with rear auxiliary air conditioning and heater systems on 2015-2019 Cadillac Escalade ESV and 2015-2019 GMC Yukon XL. This Dorman 926-837 A/C hose assembly is built for the rear HVAC layout used in these full-size SUVs, where corrosion-prone aluminum lines can lead to refrigerant loss and system failure.

The reinforced rubber construction helps reduce the installation challenges common with rigid factory lines, especially in underbody locations exposed to road debris, moisture, and corrosion. The molded assembly shape supports a cleaner fit along the vehicle routing path, while threaded ends and included seals help restore the connection points in the high-pressure side of the system.

What It Helps Repair

  • Refrigerant leaks caused by corroded factory A/C lines
  • Loss of rear cabin cooling performance
  • Damage to rigid aluminum lines from underbody exposure
  • Failed high-pressure hose routing in rear HVAC systems
  • Service issues on Cadillac Escalade ESV and GMC Yukon XL rear auxiliary A/C and heater setups

Installation Notes and Tips

Verify the vehicle uses rear auxiliary air conditioning and heater equipment before installation. Confirm the threaded end connections, hose routing, and refrigerant service requirements match the original layout. This part number, 926-837, is intended for R134A systems and includes fittings and seals as listed in the product data.

Quality Assurance

Dorman OE FIX parts are engineered to address common failure points in original equipment designs by changing the material and service approach. Part number 926-837 follows that approach with a flexible rubber hose assembly for rear HVAC service on select Cadillac Escalade ESV and GMC Yukon XL applications.
