Use a ruler or caliper to measure the diameter of the spigot threads as accurate as possible; this measurement is crucial as it will determine the size of the part needed.

This specific spigot is 1 1/8 or 1.17 inches in diameter, so a SM01.125 adapter from Spigot Masters was ordered and used.

If the hose thread outlet is standard (¾ inch), omit the adapter, as it is already the desired diameter for a common hose in the US. A vacuum breaker can still be used as long as it is the appropriate size.
