Summary

These parts allow you to connect a jerry can to a standard hose thread. Useful for both filling and emptying when RV-ing.

I suggest you print in PETG with 50% fill for strength. Depending on the tolerance of your printer, you may want to print the female slightly oversize, and the male slightly undersize. You may need to use a file or sandpaper to flatten the surfaces.

I use these to get water into jerry cans, and then dump them into my RV. When filling, avoid fully tightening the hose, or can fittings so that water can escape once the container is full to avoid damaging or bursting it.
