Mmm, Galvanic Corrosion Burger

I don’t know where they came from but somehow this facility was ~blessed~ by having some aluminum transmission line adapters in use.

Here’s one (a gas block with pressure fitting) sandwiched between flanges made of brass and nickel plated(?) brass…. similar to about 99% of all these fittings I’ve seen in service.

But wait, aren’t those a little far apart in galvanic potential?

Maaaaybe.

Gack. Note the first inner lip around where the polymer insulator is seated. This is where the RF connection is actually made. The well around it only holds the sealing ring.

No thanks.
