ENVIRO-SEAL Packing Retrofit Kits
Retrofit kits include parts to convert valves with
existing standard bonnets to the ENVIRO-SEAL
packing box construction. Refer to figure 11 for key
numbers for PTFE packing, to figure 12 for key
numbers for Graphite ULF packing, and to figure 13
for key numbers for duplex packing. PTFE kits
include keys 200, 201, 211, 212, 214, 215, 216, 217,
218, tag, and cable tie. Graphite ULF kits include
keys 200, 201, 207, 208, 209, 210, 211, 212, 214,
217, tag, and cable tie. Duplex kits include keys 200,
201, 207, 209, 211, 212, 214, 215, 216, 217, tag,
and cable tie.
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.
For part numbers of individual components in the
ENVIRO-SEAL packing kits, refer to instruction
manual ENVIRO-SEAL Packing System for
