Ordered as TFE027, this is an AS568-027 white PTFE (Teflon) 55 Shore D O-Ring measuring an inside diameter of 1.301 in (33.05 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.441 in (36.6 mm). The o-ring delivers dependable bidirectional sealing in a compact groove envelope.
PTFE (Teflon) offers one of the lowest coefficients of friction of any solid and a very wide continuous service temperature range. This material stands up to steam, nearly all industrial chemicals, and oxidizing media. Published continuous service range is -65°F (-53.9°C) to 500°F (260°C). It is not the right choice where molten alkali metals or service requiring elastic recovery are present.
Common environments for this compound include chemical processing, laboratory equipment, and semiconductor fabrication.
Stocked as TFE027 and sold individually. Nominal inside diameter is listed as 1 5/16 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
