Test Port Insert
For devices with 1/8 BSP or NPT mounting threads, the diameter of the thread is very
close to the effective sealing diameter of the O-ring fitted to the test port.
This can make it difficult to achieve a good seal. When mounting these devices, use the
test port insert (stored in the spare seals container) as shown in Figure 2-6.
