Section 5.2: Assembling the EST Extensions
• Begin by butting the O-rings against joint of each EST into the aluminum coupler. Then, insert the lower
EST into the upper EST, and slide the remaining O-ring up to the butt of that joint as well.
Figure 5.2 Figure 5.3
• Now the polyolefin heat shrink tubing can be slid over the joints and heated in order to make a firm seal
on the joints.
Figure 5.4 Figure 5.5
• The hose clamp (PN 60-6000-20) can now be slid into position (shown circled in red in figure 5.6) and
tightened to further support the EST extension assembly.
Figure 5.6
• The completed assembly should look like figure 5.7 below:
