A flexure is formed in the body partially circumscribing the plurality of apertures. A cutout is formed through the body on a common radius with the flexure. One or more bores extend from a radially inner surface of the cutout to an outer surface of the body. A heater is disposed between flexure and the plurality of apertures. The flexure and the cutout are thermal chokes which limit heat transfer thereacross from the heater.
