I recently had this issue, having purchased a MiracleGro in-line fertilizer
dispenser from the US, and needing to adapt both ends from US to UK BSP
fittings.

The solution was to order a Gardena quick-fit adapter from the US. It is US
threaded but fully Hozelock compatible. I used the Gardena ends on the
MiracleGro feeder and connected them to Hozelock ends connected to the spigot
and hose. Mated up perfectly, no leaks.
