HIGH‐SEAL and ENVIRO‐SEAL Packing Retrofit Kits
Retrofit kits include parts to convert valves with existing standard bonnets to the HIGH‐SEAL or ENVIRO‐SEAL packing
box construction. Refer to figure 17 for key numbers for HIGH‐SEAL packing. For ENVIRO‐SEAL packing, refer to figure
18 for PTFE packing key numbers, figure 19 for Graphite ULF packing key numbers, and figure 20 for duplex packing
key numbers.
Stems and packing box constructions that do not meet Emerson stem finish specifications, dimensional tolerances,
and design specifications, may adversely alter the performance of this packing kit.
