STEP 5: STUB TUBE INSTALLATION
1.
Reposition the tank in the upright position.
2.
Apply thread sealant to the Stub Tube Recommend Sealants: #2 Permatex, 3M 4200, or Permatex with
PTFE. Sealant must have PTFE. See sealant manufacturer application instructions.
3.
Screw the Stub Tube into the tank fitting.
4.
Apply Thread Sealant to the elbow and screw into Stub Tube fitting. You may need to hold the Stub Tube
fitting with a pipe wrench to avoid turning it while screwing in the elbow. As the threads tighten, pay
attention to the direction that the elbow /hose is pointing.
•
Often, the lift
’
s hull pad dead rise is shallower than that of the vessel.
To increase the dead rise
capability of the lift, the Stub Tube may need to be trimmed. See
Chart 6
for trimming the Stub
Tube and
Chart 7
for spacing hull pads. In combination, these will give you the draft of the lift
needed for your vessel.
•
Be careful not to overshoot the desired alignment since backing off the Stub Tube can cause a
leak path around the fitting.
The Stub Tube can be hand tightened such that minimal threads on
the elbow are visible.
