## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Finally one that works
  

*by C***E on Reviewed in the United States on September 15, 2023*

I think I've tried 4 different discharge line (high pressure) couplers for my gauge set.  They all had the same issue of the coupler's center pin not extending down far enough when turned fully "open" to fully depress the schrader valve in the discharge line to give me an accurate reading on the high pressure gauge.  With each coupler (including the Yellow Jacket one) I had to grab (with a glove on) the extremely hot coupler and line and squeeze them together to get an accurate high pressure reading.  This coupler finally fits well enough to open the schrader valve all the way and give me an accurate reading.

    Great replacement
  

*by A***R on Reviewed in the United States on September 20, 2022*

I love that it has its own shutoff valve. Didn’t think I would use that part of it, but I do.
