works greatUsed once so far but pulled down to 135 micron and held below 500 micron over night with new Supco guage.Unfortunately, this piece did not perform well. Been using it the last 2 months on about a dozen pump downs. Had a hard time getting a deep vacuum below 1000 microns with this in the loop. The gaskets lasted 2 months before they failed also. Would have been a great addition in my vacuum system if it had performed better.Great product does the job perfectly. I just feel that it is over priced. Your wallet may vary.Like itI saw a similar thing, or maybe the same thing, on Youtube and wanted one... so I purchased this. After delivery, I found it to be exactly what I thought it was, and what I wanted. So I'm happy with the purchase, and the seller.I ordered NEW not used and received a used one with oil al over it and a damaged o ring sending back will not purchase again.Worked liked a charm good Sealits an adaptor, piece of pipe with fittings,serves a functionSatisfecho
