Will it work on other brand watering tools?
Yes. The female threads on this item are standard garden hose threads, (GHT). It can be attached directly to the end of a garden hose or onto threaded wands, spray guns, ball valves, etc.
Is this item rated as Drinking-Water-Safe?
Not at this time. Eley has initiated a process to transition all of our watering tools to drinking water safe lead-free brass. We do not, however, have a timeline on when this change will take place.
