When your vehicle's rear air conditioning lines fail, finding the right replacement is critical for restoring cabin comfort. Our professional-grade rear AC line set kits provide everything you need for a complete, leak-free repair—engineered specifically for vehicles with rear HVAC systems.

Rear AC Line Replacement Kits with All Components Included

Each rear AC line kit includes precision-manufactured high-pressure flexible AC hose assemblies, OEM-grade o-rings, mounting hardware, heavy-duty zip ties, and detailed installation instructions. These aren't universal-fit parts—every kit is designed for direct fitment to specific makes, models, and year ranges.

Why Replace Your Rear AC Lines?

Rear air conditioning lines in SUVs and vans are particularly vulnerable to damage from road debris, corrosion, and wear. Common symptoms of compromised rear AC lines include loss of cooling performance in the rear cabin, visible refrigerant leaks, hissing sounds, or AC compressor cycling issues. Our replacement line sets restore your system to original functionality.

Installation Tips for Rear AC Line Replacement

Before beginning installation, recover all refrigerant from the system using proper AC service equipment. Inspect all connection points for corrosion or damage. Replace o-rings even if they appear intact—new seals ensure leak-free connections. After installation, vacuum the system to remove moisture before recharging with the manufacturer-specified refrigerant type and quantity.

Technical Specifications

Our rear AC line sets are manufactured from barrier-type refrigerant hose with crimped beadlock fittings. All components are compatible with both R134a and R1234yf refrigerants (verify your system type before ordering). Hoses meet SAE J2064 standards for automotive air conditioning applications.
