1/2" PRELUBRICATED PTFE YARN PACKING

APG stocks the 11690500-10, a PTFE Filament Impregnated Compression Packing supplied with a 1/2 inch square cross section. A compression packing provides field-serviceable shaft sealing that can be adjusted and topped up without disassembling the pump. Supplementary detail from the product record: 10 LB. Box - Approx. 51 FT.

Expect good resistance to steam, strong acids and bases, and oxidizing media. That behavior comes from the compound itself: PTFE Filament Impregnated is valued for a very wide continuous service temperature range and near-universal chemical inertness. It should not be specified for service in elemental fluorine at temperature or service requiring elastic recovery.

Maintenance and OEM teams specify it across pharmaceutical and biotech, food and beverage, and aggressive-media pipelines.

11690500-10 ships individually. Unit weight is approximately 10 lb. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. For a size or compound outside the standard catalog, APG can quote from a print or sample.
