General Industrial Valve Component Material
Notice of Change
Tetralon, a red-colored glass-filled PTFE material, is being discontinued by the current supplier and will be replaced by another glass-filled PTFE material. This will minimize the potential risk of a supply chain disruption. The new material will not contain the addition of an iron oxide pigment that gave Tetralon components a red color, resulting in a color change for the components listed below from red to white.
This change has no impact to product fit or function.

· N Series Severe-Service Union-Bonnet Needle Valves – stem packing supports
