​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​This unique, carbon and graphite construction packing provides plant-wide utility off a single spool. Chesterton 370 is manufactured from a high-quality carbon yarn incorporated with particles of pure graphite, high-temperature tolerant oils, and molybdenum disulfide, all of which act as long-life lubricants and blocking agents. The low-friction carbon yarn has exceptional high-temperature capability in a non-oxidizing environment. *
