Review on Anderson Metals Brass Half Union Fitting by Chris Bowden

Perfect for my MasterCool vacuum pump. I wanted to improve my vacuum time, recently bought a Yellow Jacket vacuum pump with a 1/2" connection. The original connections were 5/16" and 1/4" which didn't work. This connection worked. Flawless, I have tested it last night on a 30 lb reconstitution bottle.I was able to pull down to 500 microns in 6 minutes and 27 seconds which is surprisingly fast.Using the Fieldpiece SMAN Manifold Set the typical time is around 20-30 minutes.The fit was perfect with no burrs or blemishes the steps were real and I was able to safely connect my hoses to them excellent quality no problems at a decent price thank you very much!
