RFR Custom Fab Replacement Utility and Fuel Jug Cap, for most 2.5 and 5 gallon jugs - CNC Machined Aluminum with Polyethylene Gasket - With 3/4” NPT hole (Purple, 60100)

How "made in USA" products should be. Everything about this cap is great; goes down smooth, stays snug but releases when you want it to. The color is vivid and the machining is classy. I like that it uses a nice large sealing gasket instead of the standard O ring other caps use.
