MODIFYING AN EXISTING METAL CAP
In order to ensure that the riser cap seals properly to the probe cable and riser, we recommend that you purchase
one of the kits available for this purpose. Riser Caps from other manufacturers may require modification. If you use
your own metal riser cap, you must drill and tap it for a cord grip fitting (V-R P/N 331028-001) as follows:
1.
Remove the cap to a non-hazardous location.
2.
Drill and tap the cap for a 1/2”-14 NPT cord grip thread [Figure 11].
