Style 1200-PBI

High performance valve stem packing especially well suited for steam service. Style 1200-PBI also features an exclusive outer braided jacket of High Performance Fiber over an extruded graphite based core. This jacket integrates a nickel alloy (600) wire totally encapsulated within the aerospace grade fiber, virtually eliminating potential stem scoring. Packing also features a solid film lubricant that is non-corrosive to stems and facilitates removal of the packing set. This style combined into a packing set, can be used with challenging media such as molten salt.
