I selected an adapter to check but it came with the torch I bought with this weed torch to make it more portable for small jobs the hose on the weed burner is male threaded with a nipple end that mates with the 30# female thread on the tank. The adapter internal threads are too short to reach the hose threads when the nipple is against the gasket/O-ring in the adapter. Low cost, therefore retained for possible future applications, but not sufficient for current needs. Converting large tank accessories to small tanks seems to be a less common use making this adapter hard to find and the male thread on the mount makes it even rarer, OFW I think that's my luck. I hope the photos help someone make the right choice.
