These are composed of a ceramic tubes with a nipple of specified length “Z ”. If the length is not specified then it is the
standard length of 6 inches (152.4 mm). The number “9” signifies # 9 Alloy which is standard. Other alloy codes can be used
(see codes on page 93) Example: The part number AP11N9-4-24 signifies A 24 gauge, 11/16” O.D. Mullite tube,
24” long, and a #9 alloy nipple 4” long. Other combinations can be specified depending on your application.
