General Note:
The largest opening establishes the basic size of a reducing fitting. The largest opening is named first, except for double branch elbows where
both branches are reducing; the outlet is the largest opening and named last in both cases. In designating the openings of reducing fittings,
they should be read in the order indicated by the sequence of the numbers 1, 2, 3, 4, 5 and 6. In designating the outlets of side outlet reducing
fittings, the side outlet is named last.
