Eleaf 510 to eGo Thread Adapter (Connector) by iSmoka
Above came with my Ismoka
eleaf istick mod. This adapter was shipped with my istick which has to guard against wear. Ismoka Eleaf realize that when two metal surfaces work against each other in screwing back and forth, the softer metal will be worn. Hence, a loose thread (created from metal degrading through wear) equals no contact/firing of topper.
The adapter is a sacrificial goat to prevent a mods female threads from being worn through constant use.
The Ismoka Eleaf 510 - Ego Adapter I use is a brass base material coated with decorative chrome thin no wear resistant plating.
Cons:
Adds height to your mod. However, the flip side is I can get my fat fingers on my RDA Magma bottom casing and quickly unscrew the cap if needed.
