General Industrial Valve Component Material

General Industrial Valve Component Material

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.
Valve Series/Components Impacted:

  • N Series Severe-Service Union-Bonnet Needle Valves – stem packing supports
  • V Series Instrument Manifolds – optional reinforced PTFE flange seal
  • VE Series Instrument Manifold – optional glass filled PTFE bonnet seal packing
  • 83 Series Trunnion Ball Valve – trunnion back-up ring and stem bearing (2 ways)
  • H83 Series Trunnion Ball Valve – seat carrier back-up rings
  • 131, 133 Series Pneumatic Actuators – thrust washers
