Repair Kits

PTFE repair kits include one packing set and two anti‐extrusion washers. Graphite packing sets include two packing
rings and two anti‐extrusion rings. See table 8.

The 8510B has two packing boxes, one at the actuator end and one at the outboard end. A quantity of two of the
appropriate kit is required to repair both ends.

WARNING

Use only genuine Fisher replacement parts. Components that are not supplied by Emerson Automation Solutions should
not, under any circumstances, be used in any Fisher valve, because they may void your warranty, might adversely affect the
performance of the valve, and could cause personal injury and property damage.
