Seal Set Instructions for FE-NPT Model External
Connector
This instruction sheet is to be used as a supplement to the standard FE
seal set instructions (side one). Read both instruction sheets carefully
before installing the FE-NPT seal set.

HOUSING
changes with locking rings (Bulk Pack).
2. Assemble NPT seal set per Diagram 2 and reassemble connector as directed in the
FE connector
3. FE-NPT seal sets require up to 600 psi pilot pressure to actuate the seal. A Fastest
pilot pressure booster *(PB-1-15) or other hydraulic pressure source is needed to
reach, but not to exceed 600 psi. The pilot pressure should always be adjusted to the
lowest pressure that will give a consistent seal.
