Mazak® Isolation Ring Teflon 30x4
This ceramic ring is the second insulator from the top in the upper section of the nozzle body on the Non Contact Cutting Head on a Mark II or NTX. It is located under the Brass Base (M111B0). The ceramic version breaks easier then the teflon version, but it withstands heat better than teflon.
