It can be stainless steel, carbon metal or another substance. The extra heavy nipple has a Sch 80 pressure and has threads on each end that are used to connect two other fittings or pipe. When measuring, the length of the nipple includes the threaded area at each end. The piece is turned into place with a wrench on the hexagonal section of the extra heavy nipple. Some extra heavy nipples do not have this hexagonal area and these nipples need to be turned with a special nipple wrench. Extra heavy nipples can have ends with different sizes categorizing them as reducer or unequaled extra heavy nipples.
