This Brass hybrid adapter from Viking Stal Mods might be just what you need to turn your 20 x 1 threaded mod into a hybrid.
The adapter will make most Mods & Atomiser combination smaller in height and give a more refined hybrid look.
The adapter comes with insulator and 4 different height centre adjustable contact screws. The easiest way to install is by screwing the base to your atomiser first and then screw onto your mod. The top has an access hole for a punch or tool to help screw / unscrew the adapter.
Please make sure your mod has 20 x 1 threading before making the purchase.
The adapter is also available in 316L stainless steel.
