Update 6/21:Almost a year later and this has stood up to weekly use and abuse degassing plastisol, stabilizing wood, and degassing resin. The hose is still as good as new, and other than being a little dusty from sitting out on my bench, this vessel still holds a vacuum. No leakage, no wearing out of the silicon gasket, and no cracks that others have complained about. My initial assessment still stands: this is a fantastic value for the money and if I ever need another one, I'd buy this again in a heartbeat.Original Assessment 8/20:Great vacuum chamber for the price. I use it to degas plastisol for making soft plastic lures. Chamber easily fits two 2 cup pyrex measuring cups and holds a seal for hours. Gauge and valves are better than I expected. Hose is plenty strong and flexible for my needs. I use a standard a/c vacuum pump and I'm able to draw -30inHg vacuum. If I ever break it, this is the one i would by again to replace it. It comes with silicon washers for sealing the manifold, but i did add teflon tape for piece of mind. A great buy. I didn't need to purchase any additional adapter to get this to fit my H. Freight pump.
