Heavy-Duty Repair for 3/4" (#12) AC Lines
The TR12 EZ Flex™ Repair Kit is specifically engineered for 3/4" (0.750") Outside Diameter aluminum lines. This large-diameter size is commonly found on the suction side (low pressure) of heavy-duty trucks, vans, and rear A/C systems on SUVs (like Suburbans, Expeditions, and Econolines).

Why use the EZ Flex™ System?
Don't spend hundreds on an OEM replacement line just because of a single leak or corrosion spot. Cut out the bad section and splice in the EZ Flex™ kit in minutes.
- Permanent Fix: High-pressure crimps and durable rubber hose absorb engine vibration, preventing future cracks.
- No Special Tools: If you have a wrench and a tubing cutter, you can install this. No expensive crimping tools required.
- Flexible Install: The rubber section allows for bends and misalignment that rigid metal splices can't handle.
Technical Specifications
- Fitment: Fits 3/4" O.D. Aluminum Tube (Metric equivalent: approx 19mm)
- System Size: #12 (Commonly Suction/Return lines)
- Pressure Rating: Exceeds OEM specs for R134a and R1234yf systems.
- Made in the USA: Assembled and pressure-tested in our facility.
Standard lengths (6", 12", 24", 36") are fully returnable. However, if you select a custom length or request customized fitting ends, these are made-to-order and are NON-RETURNABLE. Please measure your gap twice!
