Flexible Grate Packing with Corrosion Inhibitor is braided from expanded grate yarn with corrosion inhibitor and has similar performance compared with other grate packing. But the corrosion inhibitor acts as a sacrificial anode to protect the valve stem and the stuffing box. This packing does not harm the shaft to save the cost for replacement of shaft. Grate packing is a highly resistant sealant used in systems with valves, faucets, and stuffing boxes, as well as other machines with watertight mechanical parts. It can be applied either to static valve stems or to moving joints. Grate packing offers high chemical resistance, great lubricity, and exnt thermal conductivity. It is the choice of many industries because it is a reliable, cost-effective, and easy-to-install sealants
