Stainless 5/8 Female to 1/2 Male Adapter
In the beer dispensing industry the 5/8" thread is widely used throughout all fittings such as keg couplers, beer tap shanks and many other fittings.
With that said, 5/8" threads are rarely used elsewhere so this adaptor changes the 5/8" thread to the common 1/2" thread that you will be able to use on a wide rage of plumbing fittings from the hardware store. This adaptor has female 5/8" on one side (so you can screw it onto keg couplers as shown below or tap shanks) and on the other side it has 1/2".
