That's a fixed C# key if it's only got a needle spring keeping it closed and with the pad cup soldered directly to the key barrel.
If you are blowing air into the joint under high pressure with the open-standing keys held closed, it's inevitable one of the closed sprung keys (the F key and fixed C# in this case) will blow open with the air pressure. The Eb and forked F vent shouldn't blow open as they're held closed by other keys.
How well does the lower joint hold a vacuum when you do a vacuum test?
