Peek insulators

[pacman]

Don't you think it's time for manufacturers to supply the above with the vast array of coils now on offer as I know a lot of people are having issues with ordinary insulators not holding up too well at the wattage people are running them at.Even selling them individually or in packs would not go amiss as they are basically all the same fitting.

I think the issue is that they use insulators of varying quality.
some quote German or American made peek, some use ceramic (which have a taste of their own).
when the 'designers' go through the catalogue picking shape, deck type, finish and price I'd say that often as not the insulators are left to the default choice.

pacman given the wide array of sales opportunities I would expect they don't want to sell them as part of the bundled goods its better business sense for them not to provide some spares in the package as it encourages people to just buy a new one rather than try and get them fixed, the average guy on the street will buy a new tank rather than pull it apart and fix it largely because they don't have the inclination to discover if it can be fixed (heck I know some people that don't even clean there kit just chuck it away when the coils it came with run out and replace it)

as to the build quality of the materials used, I rather suspect the impending regulations will see them improved in the coming months to be less problematic for the consumer anyway.

From looking at the new models coming out I'd tentatively say that there are more with press fitted positive posts even if they do have adjustable 510 pins. No chance of replacements.

Are we cross wired here.I am referring to stock coils not the tanks and the insulator on these. Triton Herakles Melo and such

Stock coils are made as disposable items the rubber insulators hold up fine for the life of the coil.
I don't see why they would bother using materials that exceed the expected lifetime of the coil itself.

Sorry pacman I took peek as meaning deck insulators

Because if they can be taken apart they can be rebuilt 

This is is an enthusiasts forum after all

Ok I get your point but these

Authentic Eleaf iJust 2 EC Dual Coil Sub Ohm Replacement Coil Heads are rebuildable coils and they don't have insulators that will last the life of the coil 

[nanotm]

just because you can rebuild in something doesn't make it an actual rebuildable deck, those tend to have the letters "RBA" somewhere in the title and they have peek insulators www.fasttech.com/search?peek%20insulator around the post

They just look like regular replacement heads to me i can't see where they say they are made to be rebuildable.

Don't get me wrong i can see the attraction of a more durable material to users who rebuild stock coils i just don't see the attraction for manufacturers to bother especially when the items are made and sold as disposable.

I'm really not sure peek would be a good choice either and it would just mean more engineering for the manufacturer.
With rubber it's simple and cheap, you pop the insulator in and it anchors itself by expanding, there's no channels needed to accommodate leads and it pushes the lead against the positive pin and the negative contact on the coil head to ensure a good contact.

Peek is a hard material you're going to have to use one mechanical method or another to anchor the insulator in place, it's not going to compress or expand to hold the wire tight against the contacts to ensure a good solid secure connection.
It just wouldn't work in those type of heads as they are now.
And yeah it is heatproof to a degree but i don't think it would last forever with a hot wire in direct contact all the time.

The whole point of replacement heads is to make em cheap throwaway items.

[SteveF]

sorry pacman but it looks like a throwaway coil that has been taken apart.
And I can't see any evidence of the insulator melting under high power.

RBA?

[SteveF]

ok so it's a £1.15 rba?
Peek would double the price.

I can't work out if it's just a bare head that you rebuild yourself like a stock coil or that there is actually a tiny deck.

Either way it highlights the exorbitant price of the stock heads and the £9 rip off for the 'rba".

I'd have to ask myself why I'm messing around rebuilding one of those when there are dedicated RTAs readily available.
