PPG PRC Desoto - PR-1764 Black AMS-3266 Class B-2 Spec Electrically Conductive Sealant | PR1764B2-2-50Z
From PPG Aerospace, this 2.5 oz PRC-1764 mixing-free Semkit sealant is electrically conductive while it inhibits corrosion on aluminum alloys as well as between dissimilar metals with long-term EMI/RFI shielding. When used in aircraft applications, this sealant can be used to maintain electrical continuity. It's resistant to aviation gas and jet fuel exposure over extended periods of time.
Service temperature: -67 degrees F (-55 C) to 250 degrees F (121 C) with intermittent temperatures up to 360 degrees F (182 C)
Best priced around great and speedy service!
Also is the better of the 2 options since it is rated at 5,000 psi, not that I go to that high of pressure but I like the safety and security knowing that my chances of it blowing up in my face are a whole lot better and I can also purchase replacement seals for them at the same shop!!!
I bought the DC PTT because I know and trust the DC quality/durability to hold up to using every day. And so far it’s the best PTT I’ve used. I have a couple other no-name PTTs and the cable sheathing is crumbling and falling off. The DC PTT has worked even in sub zero cabin temp conditions when I didn’t have a functioning heater. I bought two to have a spare but the first one has been working great for 300hrs so far.
