Lewco Style 07-024A Packing is braided from graphite-PTFE compound with lubricant. It has a very high thermal conductivity and high flexibility providing excellent volumetric stability. Lewco Style 07-024A can be used in pumps, agitators, mixers and kneader centrifugal pumps. |
| Lewco Style 07-025 Packing is braided from carbonized Polyacrylonitrile fibers that have been impregnated with PTFE emulsion. Lewco Style 07-025 is inert to almost all corrosive chemicals. It has excellent thermal conductivity. |  |
 |
Lewco Style 07-025C Packing is braided from carbon fibers that have been impregnated with graphite. Lewco Style 07-025C is an excellent choice for severe service in valve and pump applications. |
| Lewco Style 07-029A Packing is braided of Pure PTFE filament yarns and impregnated with PTFE dispersion. It is a firm high density braided packing. Lewco Style 07-029A can be used in a wide range of process chemicals and concentrated acids, valve stems, rotary shafts, reciprocating equipment and other processing equipment with high peripheral speed, rods and pistons. |  |
 |
Lewco Style 07-031 Packing combines pure graphite yarn encapsulated with multiple Inconel wire. It has a very low chloride content and excellent for high temperature/high pressure valve applications. Lewco Style 07-031 can be used in valves and some rotary applications, soot blowers and high temperature valves. It is not suitable for strong oxidizers. |
| Lewco Style 07-042B Packing is braided Inconel wire inserted carbon yarn over a homogeneous core of high temperature fibers and graphite with graphite lubrication. A corrosion inhibitor is added to protect valve stems. Lewco Style 07-042B is a high temperature valve packing. |  |
