Ordered as TFE456, this is an AS568-456 white PTFE (Teflon) 55 Shore D O-Ring built to an inside diameter of 13.475 in (342.27 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 14.025 in (356.24 mm). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.
PTFE (Teflon) is specified here for non-stick, non-contaminating surface characteristics and near-universal chemical inertness. The material holds up against strong acids and bases, oxidizing media, and solvents. The material carries a published service range of -65°F (-53.9°C) to 500°F (260°C). Applications involving molten alkali metals or elemental fluorine at temperature call for a different compound.
Common environments for this compound include laboratory equipment, semiconductor fabrication, and food and beverage.
Order part number TFE456, sold individually. Nominal inside diameter is listed as 13 1/2 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
