Extraction tube works great it came with a optional top with a valve and a optional bottom with a valve and a few extra gasketsEasy to put togetherGood value for your moneyHowever do NOT use the green dishIt does not like cold and will disfigured it self and dump out what ever you put in itThis is awesome. Came with everything. Best set up for this priceGreat product for the price. Polished finish , went together easy, you must Teflon everything before you assemble. Held vacuum for a full day, clean then use. Two tips ; first is hold onto the plastic column caps . This will let you pack then put in the freezer, second is get a different plug for the PSI plug for your gauge. As once you cut the tip to zero the pressure out it leaks since it's always on its side . The gauge is nice but you don't need it .serious leakExploded ! tearing mesh gasket
