Vapor Authority หัวเกลียวรวมอลูมิเนียมผิวหยาบ อะแดปเตอร์ 510 และชุดปลายดูด

Swapping out my old flush nut for this integrated one took about ten seconds, and the fast nut threads on smooth with no wobble at all. The drip tip set it came with is a nice bonus too.

The knurled grip on this thing makes swapping tanks so much easier than the smooth flush nut I had before. Fits flush on my 510 and the drip tip set gives me a couple of options to switch between.

Swapped this onto my mod in about ten seconds flat, way quicker than messing with the stock flush nut. The knurling gives my fingers enough bite to tighten it down without cranking on it, and the drip tip fits snug with no wobble.
