Use an approved, high grade pipe thread sealant to seal all hydraulic connections. PTFE Teflon tape (KE -
983-9000K) can be used, making sure it is applied carefully (two threads back) to prevent the tape from
being pinched by the coupler and broken off inside the pipe end. Any loose pieces of tape could travel
through the system and obstruct the flow of fluid or cause the jamming of precision fitted parts.
