I need a o ring.

[ThaFuzz]

I need the drip tip o ringfor the stock kanger subtank mini drip tip. Kanger does not sell them and they are thicker than the spares i have for my other 510 tips.1) Does anybody know what size they are? 2)where might i find them on the interwebz?

Haven't a clue on a source for you, ThaFuzz, but you might be able to get by if you wrap a turn (or two or three...) of dental floss under the existing O-ring to beef it up.

Could take your drip tip to:
Chesapeake Bay Rubber & Gasket - Buna O-Rings
They should have it. Might have to test a couple of sizes.

According to my admittedly cheap calipers, this looks to be an 8mm OD by 1.5 mm thickness o-ring. You could try the following, and see if that does the trick:
$0.80 Rubber O-Ring Seals for E-Cigarette (10-Pack) 10-pack - 8*4.9*1.5mm (OD*ID*T) at FastTech - Worldwide Free Shipping

Hope it helps and Happy vaping!
