This part is extremely handy so you can connect your ball lock disconnects to your keg coupler. It has on one side a 5/8 female thread and on the other a liquid ball lock disconnect. It is made completely from stainless steel. Note; This does not include the coupler

Liquid Ball Lock Post with 5/8" BSP Thread

If you are using any 50L Keg coupler (A-Type, D-Type ect.) and want to be versatile in what kegs you can get, then we would strongly suggest converting your couplers to 5/8" Ball lock posts, to use ball lock disconnects on your coupler to change them over quickly. 
This is for liquid only, the identifying difference is a smooth finish, no engraving band around the postengraved band around the post. A Liquid Ball lock will only fit on a liquid post.
We would also recommend using some Keg Lube around the liquid posts to prevent beer from drying and making it hard to get the disconnects off the coupler in the future.
