ENVIRO‐SEAL Packing Repair Kits
Repair kits include parts to replace the “soft” packing materials in valves that already have ENVIRO‐SEAL packing
arrangements installed or in valves that have been upgraded with ENVIRO‐SEAL retrofit kits. Refer to figure 6 for key
numbers for PTFE and Graphite ULF packing.
Stems and packing box constructions that do not meet Fisher stem finish specifications, dimensional tolerances, and
design specifications, may adversely alter the performance of this packing kit.
