*1/4" FDA PTFE YARN PACKING

This compression packing is supplied in Lubricated PTFE Filament Packing with a 1/4 inch square cross section, catalogued under part number 11700250-10. It is cut into rings and stacked in a stuffing box, then compressed by the gland to seal a rotating or reciprocating shaft. Additional detail on this item: 10 LB. Box - Approx. 233 FT.

This material stands up to nearly all industrial chemicals, solvents, and oxidizing media. That behavior comes from the compound itself: Lubricated PTFE Filament Packing is valued for non-stick, non-contaminating surface characteristics and a very wide continuous service temperature range. It is not the right choice where service requiring elastic recovery or molten alkali metals are present.

You will find this material specified across chemical processing, food and beverage, and pharmaceutical and biotech.

11700250-10 ships individually. Unit weight is approximately 10 lb. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
