Some of you may want to get the acrylic bell caps separately (that don't have the plastic chimney barrel part), and some of the metal chimney barrels. You don't have to worry about the heat getting to the plastic barrel then.
I've bought multiples of these
below from FT and they work great with no problems. Also, these bell caps will accept
any 510 drip tips. I found out the hard way (after ordering 2 lots of 5 other ones that were
first recommended on another thread)...that they were tapered inside the sticking up plastic drip tip part on it...and as a result, they wouldn't take
any drip tips except the squishy silicone ones that would then pop off too easily.
$5.02 Replacement Acrylic Bell Cap for Kayfun Mini RTA Atomizer (5-Pack) 5-pack at FastTech - Worldwide Free Shipping - Clear ones in a 5 pack, but they have them singly as well as in colors, too. Just make sure in the dropdown box to pick the ones that say
Kayfun Mini Bell Cap, Acrylic, and then the color.
Most all of the metal chimney barrels that we all ordered previously...have either been discontinued or are constantly out of stock. So, I ordered these below, and just unscrew and take off the top chimney cap part. Then use only the barrel part on the KF shorties.
$7.36 Replacement Chimney for Kayfun (5-Pack) - stainless steel / ohm logo at FastTech - Worldwide Free Shipping - They're also sold singly in the dropdown box.
ETA: There are other chimney barrels that will also work, on a variety of
different bases though, too. I've seen them discussed on threads
other than the Are You Done Stocking Up thread.
