These are my favorite drip tips.

The blue one is glass. Both serve to cool down the vape. Vapor will condense inside both and you can see it inside the glass one. Notice both have dual O-rings. That makes them very stable less likely to fall out. Sometimes, larger O-rings are needed as not all manufacturers machine the 510 drip tip hole to the same diameter or depth. The glass one is angled and I like it better as I don't have to tilt the whole rig up. Notice the wide bore on the glass one, both at the 510 end and the mouth piece. The SS one is a standard hole ie smaller. I like to use the wide bore on high airflow attys. But the SS one on the right also makes a decent tool for taking the BVC coil cartridge apart LOL.
To rebuild a cartridge simply put a screwdriver through the hole in the bottom pin like a T-handle and pull the bottom pin out, then pull the insulator out (tweezers help), grab the coil legs and pull both at the same time (fingers or wide tip/parallel jaw pliers). Helps to pull gently and wiggle. This will pull the wicking and coil out together but leave the sleeve and screen inside the cartridge body. Then remove the stock wicking and rewrap the coil with KGD and reinsert into the cartridge body, insert insulator with the outside coil leg on the outside of the insulator and the inside coil leg on the inside of the insulator. Then reinsert pin.
You can reuse the coil or make your own on a 4mm mandrel.
There is an alternate method. There is a metal sleeve in the body with two flanges/slots. You can get that whole sleeve/wick/coil assembly out at one time. First remove pin and insulator. Now place a rod or socket of the right diameter in the top and while holding the cartridge body with a pair of pliers, tap the sleeve out with a hammer. Shown below, the long ribbed SS drip tip fits perfectly for this purpose. Lightly tap the bottom of the drip tip with the hammer. The sleeve will pop out. Don’t squeeze the body with the pliers too tight as it will crush it. The bodies are thin wall brass with chrome plating. Just position the pliers so the jaws catch the top lip of the cartridge.

Then rebuild with KGD, insert insulator and pin into sleeve. Optionally rewrap paper around sleeve, I didn't. Then put that assembly into the cartridge body and squeeze together with pliers.

Awesome, thanks for the info on rewicking. Could you provide link so I can look into those drip tips?
Thanks again,
