Worst O-Ring Set Ever

This is bullshit. After only a few months, they flattened out and deformed, resulting in multiple refrigerant leaks. Having worked on cars for over 40 years, I've never seen a shittier O-ring. In my opinion, they should not be sold for car air conditioning.

Pros
  • A total of 18 of the most popular O-ring sizes used. 270 pcs rubber O-rings with 18 different sizes for most car air conditioners.
Cons
  • You could choose a newer model
