Part 1:
Assemble the Process Connection Hardware to the Terminal Head
Tools Needed:
Pipe wrench, tape measure
Components Needed: Connection hardware, terminal head
Depending on your installation, you may have to assemble a Nipple (N), Nipple-Union (NU) or Nipple-Union-Nipple (NUN) to
your terminal head (See Figure 1).
1. Using a pipe wrench, firmly tighten the components to the head. Note: The stamping on the union should face the head.
2. Measure the resulting distance from the bottom face of the head to the bottom of the connection hardware, minus 0.5”
– this will be used in determining the sensor housing dimension (Part 2).
NOTE:
For best results, use locktite or similar thread-sealer on all connections
Fig. 1
Note:
The standard EK1000 kit standardly contains 2” carbon steel nipples and unions, allowing you to assemble
connections as follows:
N = 1”
NU = 3”
NUN = 4”
For additional flexibility, you may order different length nipples. The chart below illustrates the most common options, along
with their dimensions:

Part 2:
Measuring the sensor housing
Tools Needed:
tape measure
Components Needed: housing
1A. If you are replacing a failed sensor, measure the existing sensor housing you are replacing to
determine the length of the new housing.
