Interbraid construction. Pre-lubricated yarns to provide a softer, more flexible packing with improved peripheral speed characteristics and exothermic properties. Recommended for any equipment where braided packings are commonly used. Dynamic and static applications. For the most severe services. All oxidizers and corrosives with one exception: molten alkali metals. PV factor 650000, pH range 0-14, speeds up to 1200 fpm. No glazing at higher speed applications, inert, virtually indestructible, lower coefficient of friction, thermal resistance to 500 °F/260 °C, and high compressive strength. Packaged in 10 lb boxes which may be broken for smaller orders. APG Filament Impregnated Packing, Braided, Series: Style 1169, 3/8 in Size, 500 °F, 1200 fpm Shaft Speed, 0 to 14 pH, PTFE
