55 gallon barrel bung lid with barbs

thingiverse

This is a lid/cap that will fit into the threading of a 55 gallon or 30 gallon barrel. The design includes a barb on both the inside and the outside of the lid. With this design you can attach a hose on the inside that will reach to the bottom of the barrel, and a second hose that comes out of the top and attaches to a pump. I use a standard siphon pump but you should be able to use an electric pump as well. Both of the barbs accept a 5/8 OD, 1/2" ID hose. One the inside I would suggest securing the hose to the barb with a cable tie or a hose clamp. I would also suggest using either a weight for the tube (so that it sinks to the bottom), or a rigid PVC exterior so that it is kept straight. If you need a different size barb, feel free to comment. I used this tubing: https://www.homedepot.com/p/Everbilt-1-2-in-I-D-x-5-8-in-O-D-x-10-ft-Clear-Vinyl-Tubing-T10006010/304185142?source=shoppingads&locale=en-US&mtc=Shopping-VF-F_D26P-G-D26P-26_1_PIPE_AND_FITTINGS-MULTI-NA-Feed-LIA-NA-NA-PIPE_AND_FITTINGS_General&cm_mmc=Shopping-VF-F_D26P-G-D26P-26_1_PIPE_AND_FITTINGS-MULTI-NA-Feed-LIA-NA-NA-PIPE_AND_FITTINGS_General-71700000055362044-58700005218218026-92700046076001590&gclid=CjwKCAjwxuuCBhATEiwAIIIz0c0WD8amJocvPZgbcwO5CjPhMoKICV90lp8DJjYuxVTDGGI0PkaCQBoCLBMQAvD_BwE&gclsrc=aw.ds
