Style 344BIL Mechanical Pump & Valve Packing, 1/2 in SQUARE 10 ft LENGTH

Macho O-Ring & Seal Style 344BIL Braided PTFE Pump Packing is a high-performance, chemically resistant compression packing engineered for demanding pump applications where low friction, shaft protection, and broad chemical compatibility are critical. Constructed from 100% PTFE filament and thoroughly impregnated with a PTFE suspensoidal blocking agent and proprietary break-in lubricant, this packing delivers smooth startup performance while reducing heat buildup and equipment wear. The interlock braid construction produces a packing that is soft enough to conform easily to the stuffing box, yet dense and stable enough to maintain consistent sealing under pressure. Macho 344BIL is specifically designed for rotating pump service in chemical processing, water and wastewater treatment, refining, power generation, and general industrial environments. Its exceptional chemical resistance across the full pH range of 0-14 makes it ideal for handling aggressive fluids, including acids, alkalis, solvents, oils, and corrosive process media. This packing is an excellent choice for maintenance teams seeking a reliable, shaft-friendly PTFE packing that balances sealing performance with long service life.
