PR-1770 Class B is a specialized manganese dioxide cured Permapol® P-5 polysulfide compound used for fillet sealing in fuel tanks and aircraft fuselage sealing applications. Its superior elastomeric properties are maintained even after prolonged exposure to jet fuel and aviation gas, making it a high-strength and durable option for integral fuel tank sealant needs.

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.
