622 Fugitive Emissions Packing
Style: 622 Fugitive Emissions Packing
SEPCO 622 is a braided, nonhardening valve stem packing type-tested to API 622. It does not shrink, so the set holds gland load through thermal cycles instead of relaxing into a leak path. Run it in high-temperature, high-pressure valves on steam, hydrocarbons, and nonoxidizing chemicals. It die-forms cleanly into rings for valve OEMs.
