protank2 and v5 problem

[sapper]

I have just purchased a segelei v5 and have hit a problem.It doesn't work with my 2 protank2 tanks.
It came with a protank and this works fine, It also works with a protank2 mini.
The problem is this, once the protank 2 is screwed onto the v5, I cannot draw through it.If I try without the v5 (just the protank) it's fine.If I draw whilst screwing it on, the draw gets tighter right up until it stops altogether.
I have taken the base from the protank and fitted it to the protank 2 and then the protank 2 works perfectly, if I fit the base of the protank 2 to the protank I get the same no draw problem.
Am I missing something?
It seems strange that both my protank 2 have the same problem but no other tanks.
Any help is greatly appreciated.

Has your sigeli got the small groves machined in the top of the 510 connector? my vamo and my ego batteries all have 4

you could try an air flow controller

hmm my protank 2 also has a hard draw..
Seems to have a 2.1 ohm coil @ 4 volts and i have to press button wait for hiss then take a long slow draw, to get it go vape nicely.
Might be batter with a lower ohm coil.
It is pants compared to a cheepo evod.
I'm not much help :/

One of my protanks did this on a different mod. Never worked it out, but.. I ended up using a 510 adapter with it on the other mod. It raised the height (obviously) but it worked perfectly. The only reason I never went further on investigations was that I stopped using the protanks. Sorry its not much help there. The 510 adapter as an extension definitely cured mine.

Try using the plinth that comes with the protank as well as the V5 top ring, works a treat on my Vamo V5

I've found problems with the draw on the PT2 from the moment I pulled it out the packet, what I've sussed is right at the bottom of the head where that pin lies that connects to your battery, the rubber grommet just behind it can get squished by some battery/mod setups which causes the rubber to flare out and reduce air flow.

The workarounds I've found are:
1. Remove the head after initial install and try to clip some of the excess rubber off
2. install the base of your protank into your battery/mod, screw the head in gently until just to say tight/sealed. Draw straight through the head to test airflow and if it's all good, re assemble.

It's a bit of a PITA especially if you're just wanting to quickly screw it into another battery, I've noticed the problems more significant with the heads that use those opaque silicone grommets compared to the ones that use the white rubber.

Vapeescape do an airflow regulator for 2.95 that might help
