Smok tfv4 leaking help!!!

[USACelt]

Ill put in here. Got mine about 3 weeks ago, I don't care for it as much as I would have liked. hype again.
But I have tried the triple and the rba and will report with CARFUL assembly leaks can be avoided easily. lube those O-rings!!!
The biggest problem area I see is the o-ring for the chimney. and the rba deck seal is also a problem , I pre lube with a little
juice and use a small flat head screwdriver to stuff the O-ring down in the slot as I turn in the RBA slow and easy. not a drip yet.

Got myself one for the holidays.

Using the RBA. Leaking when filling or leaking while using. Basically, just leaking. Ugh... I'll check the o-rings and whatnot the next time the tank is empty.

Hey, I'm using SMOK TVF4 with the SMOK TF-R2 RBA head and yesterday it started leaking..but I think the leakage was not on the chimney, its was bottom leakage, in 5mins my 5ml tank was completely empty

Any tips?

Also I'm vaping 70VG/30PG or 100% VG at 45-55watts and this coil runs at .29ohms

 

[bielfm]

does anyone know the inner diameter of the o-rings that i need to replace all of them?

 

[M.W.]

Same happened here. My coil was burnt out like the bride of chucky towards the end of the movie. Like a BBQ. Change the coil. I didnt vape at high watts - just the older it got the more it leaked. when i finally changed I was like HOLY CRAP. usually smoke max vg. but have some diff blends.

edit: I removed the tirade. Most unbecoming. I might take the time to swap out o-rings etc, but I'm also an M2L vaper and this thing is more for D2Lers really. It just doesn't meet my preferences.

When I received the TFV4 I immediately switched out the tri-coil for the Quad. I filled it up. Maybe took two puffs and left it. All the liquid leaked out the bottom air holes. I refilled and vaped on it for a while, now I'm going on over 2 weeks and the problem didn't re-occur.
One thing to mention is that the TFV4 box comes with a scratch off number and you can go to Smok and verify whether you have an authentic unit or counterfeit. I've heard there are counterfeits on the market.

Thanks for that tomzgreat, but I did verify the number with Smok. It's a real deal alrighty. I watched a couple youboob vids about dealing with leaks and It did go for a few hours without leaking last night and I was very thrilled that I had apparently dealt with it, but this morning I discovered it had drained out all over my previously spotless rx. (!) Even when it wasn't leaking it was either too airy, or too tight, and always too hot with a regular drip-tip. No way I would ever get used to that slip-streaming, business end of an atlas rocket type thingy. I even tried D2L and almost blew my own head off.

But the biggest problem is that I will never trust it not to leak again. Too bad cause I liked the look and the flavour production was fairly good. Ease of filling/building/cleaning/disassembly was another big plus, but your honour, them leaks.... They done me head in man.

Ouch you are hitting close to home, I have a Rx 200 I'd freak if the juice leaked all over it. I was lucky it was off the mod when it leaked. I have trust issues too Sigh..
But the Quad at 120 Watts really does rock!

That Quad is a nifty little device. The 510 drip-pan would probably hold more juice than some tanks! Copper pin is a nice touch too. Copper is soft, but imo still the best material to use for contacts, but I digress...

A bit more research and inspection reveals the leak definitely originates at the rba/chimney o-ring. If I fill below that level and keep the TFV4 bolt-upright it does not leak at all. However it also will not fire if I attach the head to the top-cap assy first, then screw the deck on as suggested in several leak fix vids. The "rca" head to base contact points do not touch when assembled snug enough to stop the leak, so I will root through my o-ring bins as well as loan the spare chimney o-ring to my supplier and see if he can't track down a couple food grade and heat resistant versions in a slightly larger thickness — if available. That problem would be easily dealt with by simply making either the base pin spring loaded, or by making that connection a slip-fit instead of a threaded join.

Blast. It really is an extreme bummer that this thing leaks. It vapes extremely well and is possibly the easiest to build, fill and clean rta I have yet used.

BTW, I disassembled and cleaned my rx yesterday and while I was at it performed the wire upgrades with better screws and ultrasonic-bathed the 510 itself. I was stunned to see how much juice leaked past the 510 "seal" and onto the board itself. Good thing I didn't fire it after the dam burst. If/when the 510 fails Imma gonna cut that thing open and inspect the spring in there. It must be a weak or small/soft spring. I used a some really flexible 14 gauge tinned copper "marine grade" cable (Ancor) and that seems not to impede movement of the pin as much as the stiff, cheap oem wire might. The stiffness of that wire is what I figure may be causing stuck pin issues, but the jury remains out on that. That and the fact that the seal is pretty much useless and also too inflexible. It's more a soft plastic than any kind of seal like material. Cleaning it might be what helped most?

edit: Actually, that base pin in the TFV4 is kinda spring loaded, but the travel is too short to span the gap!

edit x 2: Not spring loaded, but it can be pressed out of the base. Maybe a little magnet-spacer will do the trick? (of course it will not, it's stainless steel you dummy) That will probably mess up the TC function though... Blast!

You are about the 3rd or 4th person (self included) experiencing this on the Quad. The Triples do not do this.

Regarding Quad, don't prime them, use max VG and fire it right up at 75 watts or higher and keep fingers crossed the 1st tank or 2. The seem prone to flood upon breaking in. My 3rd-6th tanks have been fine.

Good luck.

Thanks for this advise, helps me a lot. No leaking anymore, i do not prime coil and went straight tp the 75w and it works great

Hey everyone,

I'm new here, and I was having a serious leaking issue with my TFV4. I was using 70/30 VG/PG, and after installing a new triple coil head, I had juice leaking out of the air holes at the base of my tank every time I refilled it. Upon taking the tank back to my local vape shop, the guy that worked there helped me troubleshoot it, and we found that I had damaged the O-ring on the coil head itself. I washed the whole thing out, put another coil in, and I was good to go!

Also, many of you may already know this, but I've found it better to use a lower VG juice during the colder months, and Max VG during the warmer months. Outdoor temperature will naturally affect the viscosity of your juice!

Hope this helps somebody!

I had the same problem. It's Smok's o-rings, too small and fragil. I got these and it works perfect. Also DON"T over tighten it will deform the o-rings and it WILL leak.

Smok TFV4 RBA / Coil O-Ring - Replacement - No More Leaks! (Set Of 3 Per Order) on ebay.

There are definitely a bunch of clones out there. My wife, not a vaper, thought she'd buy me a couple off of Ebay and they turned out to be clones. Both leaked all over the place. I did my research and found out that a genuine Smok tank will have a black screwdriver that comes with it. Both of the clone tanks I received had blue screwdrivers, also the codes came back as clones. Check out this site if you aren't sure. 5 Ways to Verify if Your TFV4 is Authentic or Fake --SMOK® Being with you for all great vaping time!

I'd still like to find a way to use these tanks. Tried quite a few of the suggestions here, but none have worked. Gonna check the o-rings again because that seems to be the most likely culprit.

 

[niczgreat]

I'm on about 90 days with my TFV4 and the leaking problem pretty much dissapeared it only occurs if I'm dumb enough to fill it, become distracted, and then not close the top.

I was lucky the one I bought off of Ebay was verified authentic at the Smok website.

I'm new to vaping and and the tfv4 and cube 2 was my first buy. I've had non stop leaking from day one. The whole tank would empty within a few hours. Im an aircraft engineer so have access to every seal possible and have tried replacing them all, didn't work. Have replaced the seal in the top where you refill, didn't work. Have tried 5 different quad coils and wasted a lot of juice!!! I genuinely wanted to throw the thing away but don't give up!!! I was so fed up of this thing I turned the wattage up to 100 and thought I'm just going to pull on this thing like mad before the juice gets the chance to leak!!! Not leaked since. I genuinely think it was a case of turning up the power and sealing that cotton or wadding, whatever it's called? I have tried everything that was mention in all these posts and turning up the wattage and puffing like mad was the fix. Don't give up on this tank guys! I almost did but once you fix it, best feeling ever!

My friend just got one and its doing the same thing with the triple coil. I have a quad coil and mine has never leaked.

 

[NYCVape]

Got a tfv4, was so happy. Leaked like mad. Changed from Quad, seemed ok for a bit, then the juice would just drip out of the air holes. [Removed] Decided it was a bum tank and got another -- same problem.

Later, bought a SMOK CUBE II, now it won't take a charge -- have to pull the batteries out to charge them.

Not going to get fooled a 4th time. SMOK products have a serious quality control issue, IMHO.
