Not understanding what the insulator does for the RDA positive post

I have an El Cabron with a mostly melted insulator on the positive post. I think it has been like that since I got it. It is still working with no apparent issues. I have more insulators. Will replacing the mostly melted insulator with a new one change how it performs?

If the insulator was completely gone would the RDA completely stop working giving me an error on a regulated mod? This RDA is strictly used for my mechanical mods.

Thanks

Oh, so I guess I should change it tomorrow before I rebuild it. There is still some there but not much.

That insulator prevents the positive post (connected to positive of your battery) and the negative posts (connected to the negative of your battery) from connecting. If the insulator were to fully melt and the positive and negative touch, it creates a short, which will either vent a battery, or have it go into Thermal Runaway, which leads to a BOOMSTICK in your hands. Insulators should always be maintained and in good working order, for every ones safety :)

The good thing is I compared it to the extra deck in the pic on RBAvapor. It is fine. Thanks for all the information. I will watch these. Good info.

Insulator holds the positive post in place, so besides the above comments about a short, the post wouldn't stay in the RDA at all if the insulator were to fail completely. It would be unusable since the post would just flop around. Plus, any liquid you dripped would just pour out of the resulting hole in the bottom of the RDA.

How did you melt it? If it was from doing dry burns, I have found that putting a little water in the juice wells of the RDA prevents the insulator from melting. The water will boil instead of the insulator melting.

You've heard of mods catching fire, going *boom*, and injuring people, right? Those batteries contain a terrific amount of energy. On a mech mod there's little to prevent the battery from trying to release it all in one go.

This info is (obviously) well-intentioned, but misleading (sorry zaroba). The insulator exists to keep the positive and negative poles separate. That's all.

Btw, materials that are proven to withstand high temps and NOT conduct electricity are usually used as insulators. Delrin melts @ 173C and is sometimes used as an insulator. It's about 1/10th the price of PEEK and so some mfg's try to save a few pennies. PEEK is the ideal (as it's melting point @ 373C is much higher than Delrin). Make sure you replace with PEEK.

In some applications they don't just insulate, they also seal and help secure other parts. zaroba was correct.

Ok any insulator can serve the purpose of a gasket in this application. So it's dual purpose... but the the singular basic function is to insulate the positive pole of the battery (which is my main point)... the rest is just coincidental to the application. To say the insulator is there to hold the positive pole in place is way off base (even though oddly enough it works that way) it's NOT why it's there.

His comment was actually an additive to mine where I already stated it was to isolate the positive and the negative, so everyone is right :D

Yeah, guess I must've been... was speaking in absolutes, for the 'why' of an insulator... sorry i posted.

Thread title -
Not understanding what the insulator does for the RDA positive post

The positive post insulator in an RDA serves more than one purpose. I'm not sure why you say that's misleading when that's exactly what they do. Your derailment makes no sense at all.

yeah ok, since you want to push this issue; it's a floor wax and a desert topping. (I've already explained what I meant. I think most folks will get it.)

No, I'm not high. Sometimes I wish but... Anyway... No the sky really isn't blue. That's just the way we see it most of the time.

You mean like a Cactus, Armadillo, or a random cow skull?

(sorry I just can't help myself in these situations)

Is anything really the color it looks, or just the color the light reflecting off of it looks? Why argue this crap...
