STEP 5: STUB TUBE INSTALLATION
1.
Reposition the tank in the upright position.
2.
Apply thread sealant to the Stub Tube threads. Some recommend sealants: #2 Permatex, 3M 4200, or
Permatex with PTFE. See sealant manufacturer application instructions.
3.
Screw the Stub Tube into the tank. As the threads tighten, pay attention to the direction that the elbow/
hose is pointing.
•
Often, the lift
’
s hull pad dead riser 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.
