My Subtank is really starting to taste BAD!

[Submarine123]

I'm using a Subtank Nano on the KBOX. Should be absolutely no problems.

But my coils (both the 0.5 and 1.0) are tasting awful. I prime them great, I make sure everythings good and secure, and I'm using a 75%-ish VG juice.

But I can't go above 20 watts with two new packs of coils I have, and especially on the 1.0 coils, that's ridiculous. I'll get a vaporized rubber taste that tastes like the worst clearomizer coil I've ever come across.

Dry cotton should just have sort of a cottony, almost doggy or smokey taste. But this is a pure rubbery flavor. Are the gromets going to crap? These things should be built for Sub-Ohm vaping!

I have no clue what's wrong but I can't use this thing anymore.

I'm also getting more juice in my mouth than I would if I drank it. These coils have started to spit and spew like nothing I've seen. I've used these coils for months and could always go up to 30 watts, no issues!

its not your coils , it is your tank , give me a few secconds to see the nano and what it consists of and I will send you what you need to do

Are the coils authentic? Did you pull one and check the grommets for charring/melting/distorting? Try cleaning the contacts in the AFC?

How do you know it's the tank that's the problem, if you dont know what a Nano even looks like?

 

[miro011]

k , tell me if you have that o-ring on the airflow base , it is transparent , the 2nd piece in this picture , do you have that o-ring ?

because I have the mini , same happend to me until I realized that I am missing this o-ring , the absence of that o-ring can ruin your tank

See that black o-ring ?

 

[miro011]

if you have it , replace the glass

 

[Submarine123]

Yeah it's got that transparent ring. There's a section on my white o-ring that's always looked slightly eaten away (a portion of it is stark white and a little shrunken, as though it melted a tad, but it was like that out of the box...)

did these occ heads work good before ?

[Submarine123]

Hard to say. I always would taste the rubbery taste very severe if I went anything above 30 watts, but 30 and below, it was always good. Really good. And I've always had a tiny bit of spitting but it's been nothing like the shower these recent packs have given my mouth...

Aside from mechanical damage or leaking, not having that ring wouldnt ruin the tank. That ring should not change the taste of the vapor in any way. It's just a seal.

If OP's tank worked fine before, but went to hell with a new pack of coils, I would first suspect knock-off coils. They're hard to identify, but generally perform like crap due to sub-standard materials and cleaning. Pick up some authentics from a trusted source and see if the problem goes away. Until you get a chance to, I'd inspect the grommets on a used "bad" coil for charring/burning/melting, and give the contacts and threads of the AFC a good cleaning with alcohol and inspect for any oxidization/discoloration.

I don't think kanger makes a 1.0 coil I think .5 1.2 and 1.5 for sub tanks that is.

That faint slap you heard waaay off in the distance was me smacking my forehead that hard. Cant beleive i missed that.
Yeah, knockoff coils for sure.

Exactly I got some from FT AND THEY WERE TERRIBLE BUT REALLY CHEAP BIG SUPRISE.

The 1.0 ones I'm talking about are 1.2 but I just called them that... I just checked and these are the real deal. I've cleaned everything up and I have no clue. At 25 watts, this 1.2 coil about made me puke. It's horrible, tastes like burning rubber. I'm using Charlie Noble's Custard. It's thick but anything thinner is a sheer mouthful of juice.

Call me crazy, but the burnt rubber taste might be from..... burnt rubber. Check all your seals, then change em anyway and clean the tank really really well. Get a new pack of coils maybe. They should have an authenticity sticker on em. Check with your retailer for a refund if possible.

They've gone through a few different types of insulators on the rebuildable section for similar issues. I've noticed the OCC coils have changed insulators as well. Maybe you found some old stock, most of mine have been red for the last couple of months, before that there was white and I think I've seen black too but I can't find one in my bowl of used coils right now.

I've had some issues with rubbery tasting OCC coils. They were the ones with the white insulator. Not burnt rubber, just rubber. I've had OCC coils with red insulators lately and there has been no rubber taste.

There was another thread that discussed that the coils with white insulators are an older version (red being newer, but not sure if newest).

I've had poor flavour from these OCC coils for a good while now though. Looking forward to trying the BVC OCC version.
