I got fed up with trying to hold a funnel while decanting into/filling my 25 litre containers/fuel tank for my diesel generator, so I designed this hands-free screw in spigot with a large opening and an air return pipe to make fast splash free filling. Tough and durable.
Sealed with a flush fitting and a secondary O-ring, print-in-place components, so you can't remove the cap from the spout helps stop you losing either (spigot can still be rotated), attaching loop added if you want to tie it to your container's handle.
If you would like it in a specific colour (standard is black) just message either before or after purchase, i usually have most colour in stock.
