1/2" PRELUBRICATED PTFE YARN PACKING

APG stocks the 11690500-05, a PTFE Filament Impregnated Packing Compression Packing measuring a 1/2 inch square cross section. A compression packing offers the most economical repairable shaft seal for pumps and valves. Source specification: 5 LB. Box - Approx. 26 FT.

PTFE Filament Impregnated Packing is specified here for near-universal chemical inertness and one of the lowest coefficients of friction of any solid. Expect good resistance to solvents, steam, and oxidizing media. Applications involving service requiring elastic recovery or elemental fluorine at temperature call for a different compound.

Common environments for this compound include laboratory equipment, chemical processing, and aggressive-media pipelines.

Order part number 11690500-05, sold individually. Unit weight is approximately 5 lb. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
