The threaded lid is new. It was designed specially for our f6.5xe gallon fermenter. A few twists of the wrist and it seals tight with the red FDA approved o-ring. Everything is included with our f6.5xe fermenter ready to brew. Two valves, two EZ seal fittings, threaded lid, Red O-Ring plus our height adjustable stand. The new threaded lid is a big four inches across so you can reach your hand inside for easy cleaning.
