In 2011, Teflon Disks were replaced with Hycar Disks in all VAV valve assemblies. The Teflon Disks were kept in the High Temperature Repair Kits at that time. A change is underway to fully obsolete the Teflon Disks and replace with Hycar Disks once current inventory is exhausted. This change does not affect the form, fit, or function of the parts and the temperature rating remains unchanged.

A list of the affected kits is below:
