5/16" FDA PTFE YARN PACKING

FDA Lubricated PTFE Filament Pump Packing, 5/16 inch x 133 feet is an industrial sealing product for rotating shafts, valve stems, glands, stuffing boxes and related maintenance applications. The product uses lubricated PTFE filament construction designed for low-friction sealing in pumps, valves, and processing equipment. The 5/16 inch profile and 133 feet length make the size easy to compare against existing equipment, stuffing box requirements, flange layouts, or maintenance inventory. This style of packing is commonly used around stuffing boxes, glands, rotating shafts, valve stems, and other areas where controlled compression helps limit leakage. Buyers can evaluate it as pump packing, compression packing, valve packing, gland packing, or braided packing depending on the equipment and service conditions. It is a practical fit for maintenance teams, resellers, and industrial buyers who need clear material identification before comparing final specifications. Because the source item identifies FDA PTFE yarn packing, it is suitable for buyers evaluating food processing and clean sealing applications where FDA PTFE material language is required. The listed packaging detail, 10 lb. box - approx. 133 ft., adds practical context for purchasing, stocking, and matching the product to job requirements.
