An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
The material holds up against steam, nearly all industrial chemicals, and solvents. PTFE (Teflon) offers non-stick, non-contaminating surface characteristics and near-universal chemical inertness. Service temperature is rated from -65°F (-53.9°C) through 500°F (260°C).
Common environments for this compound include semiconductor fabrication, pharmaceutical and biotech, and laboratory equipment.
Stocked as TFE150 and sold individually. Nominal inside diameter is listed as 2 7/8 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
