Are gas fittings tightened clockwise or anti-clockwise?
clockwise
anti-clockwise
it depends on the gas
there is no standard
Some gas fittings use reverse threads to prevent disastrous misconnections. For example, oxygen fittings are right-handed, but acetylene and other flammable gases use left-handed fittings.
