## Customer Reviews

### ⭐⭐ 2.0 out of 5 stars







  
  
    Poor quality on milling.
  

*by S***1 on Reviewed in the United States on February 19, 2020*

Like: The parts arrived in a timely manner. All parts were there.Dislikes: Finding out gaskets on both elbows started leaking upon start up. Pulled elbows and found the cause to be poor quality milling surfaces on all four parts. So, I took the parts to local machine shop and paid to have them done right.
