Designed to simplify leak detection and repair in the hydrocarbon and chemical processing industries, the ultra-low emission, high-temperature valve stem spool packing meets global emissions standards. Style 212-ULE is composed of two types of graphite packing. One of the braids is manufactured from a proprietary yarn consisting of several strands of high purity Graph-Lock contained by an Inconel filament jacket. The wire filament is 0.004" in diameter, making the finished braid non-scoring and thermally conductive. The other braid is manufactured from graphite fiber, reinforced flexible graphite yarns and high-purity graphite filament yarns. The packing is self-lubricating, nonhardening, dimensionally stable, impervious to gases and fluids, and corrosion resistant.
