7/16" TREATED PTFE YARN PACKING

APG stocks the 11740437-05, a TFE Filament Compression Packing with a 7/16 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: 5 LB. Box - Approx. 37 FT.

The compound resists strong acids and bases, steam, and solvents. That behavior comes from the compound itself: TFE Filament is valued for a very wide continuous service temperature range and near-universal chemical inertness. Applications involving service requiring elastic recovery or molten alkali metals call for a different compound.

Common environments for this compound include chemical processing, food and beverage, and pharmaceutical and biotech.

This item is sold individually under part number 11740437-05. Unit weight is approximately 5 lb. Application requirements vary, so validate compatibility with your process conditions prior to installation.
