OP Plug Orifice

Brass propane fittings are essential attachments for effective propane tank use. Brass attachments come in many forms: adaptors, t-fittings, y-separator adaptors, caps or plugs. Propane and Natural Gas Are Supplied at Different Pressures: Cooktop burners typically supply about 40,000 BTUs per hour. A propane stove orifice size is about 0.082 inches (drill size 45), but the valve on a similar stove that uses natural gas needs an orifice that is almost 0.125 inches (drill size 35).
