1/4" FDA PTFE YARN PACKING

11700250-01 is a Lubricated PTFE Filament Compression Packing with a 1/4 inch square cross section. In service, this compression packing provides field-serviceable shaft sealing that can be adjusted and topped up without disassembling the pump. Source specification: 1 LB. Box - Approx. 24 FT.

This material stands up to solvents, nearly all industrial chemicals, and strong acids and bases. That behavior comes from the compound itself: Lubricated PTFE Filament is valued for excellent dielectric properties and a very wide continuous service temperature range. Exposure to service requiring elastic recovery or elemental fluorine at temperature will shorten service life.

The compound meets FDA requirements for food contact. You will find this material specified across semiconductor fabrication, chemical processing, and food and beverage.

11700250-01 ships individually. Unit weight is approximately 1 lb. Check the compound against your process media, pressure and temperature before committing to a design.
