1/4" TREATED PTFE YARN PACKING

Part number 11740250-01 is a TFE Filament Compression Packing built to a 1/4 inch square cross section. A compression packing seals the shaft while allowing controlled leakage that lubricates and cools the packing set. Supplementary detail from the product record: 1 LB. Box - Approx. 19 FT.

This material stands up to steam, solvents, and strong acids and bases. That behavior comes from the compound itself: TFE Filament is specified for one of the lowest coefficients of friction of any solid and near-universal chemical inertness. Exposure to elemental fluorine at temperature or molten alkali metals will shorten service life.

Common environments for this compound include chemical processing, semiconductor fabrication, and aggressive-media pipelines.

11740250-01 ships individually. Unit weight is approximately 1 lb. As always, verify media compatibility and operating conditions against the requirements of your specific application. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
