Fitting size on gas regulator

[jadnashua]

Just got a new NG barbeque grill. Was hoping to use the old hose which was only a year or so old, but the fittings are too small. The manual doesn't say - I sent a message to their tech support, but that won't be until probably late tomorrow before I get a response. The threaded fitting (male) is just under 3/4" in diameter across the threaded portion (a 3/4" open end wrench has just a very small slop, so the diameter is just under 3/4". Is that a 1/2" gas fitting? Wanted to do some surfing to check out supply.

The outside diameter of 1/2" IPS should be around 5/8".
Hopefully the thread IS IPS (8 TPI), I wonder if the MFG doesn't set it up so you'll have tyo buy their parts....
