Stainless 5/8" BSP Female to 1/2" BSP Male Adapter
In the beer dispensing industry the 5/8inch 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 inch thread to the common 1/2inch 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 left or tap shanks) and on the other side it has 1/2 inch.
NOTE: These have 1/2" BSP and 5/8" BSP thread standards and will fit to 1/2" BSP and 5/8" BSP Threads. Please check the BSP thread standards to make sure this is the fitting you require as a 1/2" BSP and 5/8" BSP thread standard does not mean diameter of 1/2" and 5/8". If you look up BSP thread standards in Wikipedia you will find a table with the actual diameter sizes relating to these 2 thread standards
