TOP SEALING PTFE Asbestos Gland Packing PA103 is crafted from the highest quality white asbestos fibers, enriched with a PTFE dispersion for enhanced performance. The optional addition of a lubricant can further optimize its properties. This asbestos PTFE packing boasts a soft texture, making it an excellent choice for sealing in pumps handling liquid chemicals. For reciprocating pumps or applications with linear velocities up to 10 m/s, we recommend using asbestos packing that has been impregnated with lubricants to ensure optimal sealing efficiency and durability.
