Our Jug Plug works great with any Utility Jug with a 3/4" NPT thread. Remove the nozzle from the cap and screw the Jug Plug in for safe storage and transportation. Wrapping the Jug Plug in Teflon tape is recommended when screwing it into our Billet Aluminum VP, LC2 or Sunoco Jug Cap. Teflon tape is not required when screwing the Jug Plug into a standard plastic cap. You'll want to check out the anodized colors for more customization!
