… is better than two redundant untested seals. In last week’s tip, I said that test ports are a key component of your subsea connector design because they allow you to verify seal integrity.
This week, I’m showing the same diagram again because I want to quickly address why there are two seals in the first place.
The reason you have two seals is to be able to positively confirm the integrity of your primary seal while pushing against it from the same direction seawater would push against it. Food for thought: your test port defeats the second seal.
So, if you’re wondering which of the seals is the primary seal … I’ll answer that in next week’s tip.
