TL;DR
A gas shutoff cock is the quarter-turn plug or ball valve installed in a fuel-gas line to isolate a branch or appliance, operated by a flat key, tee handle, or lever that visually shows open or closed by its orientation. The fuel gas code requires one within 6 feet of each appliance and in the same room, ahead of the flexible connector and union so the appliance can be removed with the line dead.
What it means
A gas shutoff cock is the quarter-turn plug or ball valve installed in a fuel-gas line to isolate a branch or appliance, operated by a flat key, tee handle, or lever that visually shows open or closed by its orientation. The fuel gas code requires one within 6 feet of each appliance and in the same room, ahead of the flexible connector and union so the appliance can be removed with the line dead. Older tapered plug cocks seize and leak with age, so plumbers commonly swap them for listed ball-style valves during appliance changes.
