The Dorman 926-834 is a flexible rubber A/C line assembly crafted to simplify under-vehicle installation. It features reinforced internal construction and corrosion-resistant aluminum fittings, plus a complete kit with high-side and low-side lines, new O-rings, and mounting bolts. Best for technicians working on Ford models needing a rear A/C line repair or replacement. Caution: verify vehicle compatibility before ordering to ensure the rear kit fits your model year.
Dorman 926-964 Auxiliary A/C Line Assembly
This Dorman kit also uses flexible rubber lines to ease installation and is reinforced for durability with aluminum fittings. It includes both high-pressure and low-pressure lines, along with new O-rings and mounting bolts for a complete repair package. Best for general auxiliary line work where space under the vehicle is tight. Limitation: ensure the kit matches your exact vehicle year and model for proper fitment.
FE37190 Complete Rear AC Line Set
This rear A/C line set is designed for specific Ford and Lincoln models, providing a complete rear line replacement. It helps restore rear cooling by replacing leaking lines with a ready-to-install kit. Best for Ford Explorer, Ford Flex, and Lincoln MKT owners facing rear-line leaks. Caution: compatibility is model-specific; confirm fitment before purchase.

The TR6-12C is a 3/8″ O.D. extended-length splice solution designed to repair or replace sections up to 12 inches. It emphasizes easy installation and quick restoration of cool air. Best for quick field fixes or temporary splicing when full line replacement isn’t feasible. Limitation: not a full line kit—best used as part of a broader repair plan.
Auto Cooling Solutions EZ Flex TR8
TR8 is an EZ flex solution for flexible 1/2″ O.D. tubing. It’s designed for straightforward field splicing and installation, with an emphasis on quick restoration of airflow. Best for on-the-spot repairs where simple splices are sufficient. Caution: verify that the 5/8″ or 1/2″ O.D. size matches your existing line before ordering.
Buying Guide
What should I consider when choosing flexible A/C lines?
- Compatibility: Confirm vehicle make, model, and year to ensure correct line size and fittings.
- Material and durability: Flexible rubber lines with aluminum fittings resist corrosion and ease installation, especially in tight spaces.
- Kit contents: Look for complete kits that include O-rings, bolts, and mounting hardware to avoid additional shopping trips.
- Length and routing: Choose lines sized to fit the intended routing without excessive bending or stress.
- Rear vs. under-hood: Rear-line sets are specialized; ensure the kit targets the rear system if needed.
How do I assess a “complete kit” versus a partial kit?
- A complete kit includes all required connectors, seals, and hardware for a full replacement.
- A partial kit may require separate purchases for O-rings, gaskets, or mounting hardware.
- This matters for installation time and reliability, as missing seals can cause leaks.
What installation challenges should I expect with flexible lines?
- Routing around existing components can be tricky; plan paths before removing old lines.
- Ensuring clean connections with the correct O-rings is essential to prevent leaks.
- Flexible lines can sag if not properly secured, which may affect performance.
Are affordable options reliable for long-term use?
- Quality materials and reinforced fittings increase durability, but verify warranty terms and return policies.
- OEM or OE-replacement-style kits tend to offer better compatibility and longevity.
