Fat Daddy Vapes 510 V4
These are Fat Daddy Vapes 510 Connectors Version 4. The 22mm sizes are available with short threads or longer threads. Version 4 no longer uses 22mm locking washers, instead the 22mm size is all one solid piece of it’s own. Also, the 15.5mm size has a greater thickness but we do carry the low profile version which is very thin. Please review pictures to be sure you’re choosing the V4 variant you wish.
Thread Dimensions:
510 V4 Long Thread: 15.40mm
