1
00:00:00.000 --> 00:00:04.000
External hydrostatic pressure rises with water head.

2
00:00:04.000 --> 00:00:08.000
Seal duty depends on pressure differential and temperature.

3
00:00:08.000 --> 00:00:12.000
Where compensation exists, verify range and response.

4
00:00:12.000 --> 00:00:16.000
External-pressure rating is not seal differential rating.
