The Ceram Back Elbow has a jacket across the back of
the core Elbow which is approximately 1/2” of Ceramic
compound. This compound has a MoHs hardness of 9+.
The Ceramic jacket and core Elbow is then wrapped
with an exterior material to maintain hoop strength.
Once the core Elbow has worn through, the abrasion is
transferred to the Ceramic outer jacket. The core also
acts as a static conductor.
