Heavy-Duty Repair for 9/16" (#14.5) AC Lines

The TR14.5 EZ Flex™ Repair Kit is specifically engineered for 9/16" (0.57") 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).

Not sure if you have a 9/16" line? View our AC Line Sizing Guide before you buy to ensure a perfect fit.

Why use the EZ Flex™ System?

Don't spend hundreds on a massive 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 9/16" O.D. Aluminum Tube
  • System Size: #14.5 (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.
⚠️ Custom Order Note:

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!

Installation Overview

  1. Cut: Remove the damaged section of your 9/16" line.
  2. Deburr: File the cut edges smooth (Critical to prevent O-ring damage).
  3. Tighten: Slide the compression nuts on and tighten to create a leak-proof seal.
