This PTFE Sanitary Gasket is engineered for extreme-duty aseptic environments, providing an absolute, chemically inert seal between 25mm Tri-Clamp flanges. Highly resistant to VHP and aggressive sporicides, it is the premier choice for zero-leach, high-purity air sampling connections.

While silicone offers flexibility, PTFE (Polytetrafluoroethylene/Teflon) offers unmatched chemical resistance and purity. This PTFE Sanitary Gasket is the ultimate sealing ring for sanitary flange connections in critical pharmaceutical cleanrooms. Because PTFE is virtually inert and non-stick, it will not shed particulates, degrade under Vaporized Hydrogen Peroxide (VHP), or adhere to the stainless steel flanges over time, making it ideal for permanent or heavily sterilized sampling arrays.
Key Features & Benefits
Extreme Chemical Inertness: Fully compatible with all known cleanroom sterilization agents, including ozone, VHP, and high-concentration sporicides.
Zero Particulate Shedding: The hard, smooth surface of PTFE ensures no microscopic material is stripped away by high-velocity airflow.
Temperature Resistant: Easily withstands repeated high-temperature autoclave cycles without warping or losing dimensional stability.
Applications
VHP-sterilized isolators and high-grade compounding hoods
Critical pneumatic lines requiring zero risk of chemical degradation
