The Dorman 926-837 is an OE FIX rear auxiliary air conditioning line assembly designed to solve a common failure problem found in long-wheelbase GM SUVs. This complete replacement kit addresses the issue of factory aluminum A/C lines that corrode when exposed to road salt, moisture, and other environmental elements, leading to refrigerant leaks and air conditioning system failure.

Key Features:

• Improved Design: Features flexible reinforced rubber construction instead of rigid aluminum, simplifying installation under the vehicle and resisting corrosion
• Complete Kit: Includes both high-side and low-side refrigerant lines, new O-rings, and mounting hardware for a comprehensive repair
• Durable Construction: Internally reinforced rubber hoses with corrosion-resistant aluminum fittings for long-term reliability
• Quality Tested: Undergoes rigorous try-on testing, corrosion testing, and material validation to ensure proper fit and extended service life
• Time-Saving Solution: Flexible line design makes routing and installation significantly easier than working with one-piece rigid aluminum lines

This Dorman OE FIX assembly provides a direct replacement solution for deteriorated rear auxiliary A/C lines, restoring full climate control function to rear passenger areas in extended-length SUVs. The flexible rubber construction not only simplifies the repair process but also provides better resistance to the environmental conditions that caused the original failure.
