PTFE Braided Packing with Silicone Core
Braided from 100% modified PTFE yarn, free of any additives or grease. With low friction, high lubricity and non-contamination, stable against strongly corrosive media, used for corrosive pump and valve sealing, especially where hygiene grades are required. The central silicone core provides durable elastic compensation, maintaining excellent sealing under heavy vibration, axial movement and bounce. Suitable for all media except fuming sulfuric acid, fuming nitric acid, aqua regia, fluorine and other strong oxidizers.
