Was looking back at some photos from November 2008 when I had for the first time a chance to put my hands on the API-622 rig. This one was built by Yarmouth Research in Maine where we were working on getting a full understanding of what would become the gold standard of emissions valve sealing.
Now almost 9 years later the way this one test has forced packing manufacturers move the needle to make LowE valve sealing a realty. Back in these photos the national limit at most plants were 10,000 ppm compared to 100 ppm today. My favorite analogy is if the Cafe requirements for cars would of changed that drastically you could drive from Boston to Los Angeles on one gallon of gas.
