SM480V overhaul deep vacuum modification.

These piston O-ring valve assemblies are available directly from Fieldpiece when it comes time to rebuild you just order them fast easy. If you watched my previous videos on this manifold as I was testing it and taking note and recording watch the micron decay test. And then every time I did the addition of a hose or different positions of valves you can actually see the difference in the micron reading. After this video of us installing the silicone grease I will make another video once again pulling a vacuum on the manifold and you will see the difference when you compare it to the first video without the addition installation of the silicone grease. This is a good thing about a micrometer you can actually measure and see my new differences in performance of any equipment that you work on. If this is your first video of mine you were watching and you were interested in this particular refrigerant manifold it also has the ability to do high-pressure nitrogen decay test and be able to watch the decay leak rate of vacuum down into the 1/10 of a psi of leak rate. This is something you could never do on a regular analog gauge set using pressure.

Including the ability to read microns instead of inches of mercury you can see and read lakes that you would’ve never been able to see with an analog gauge set under vacuum.
