The Drip Tip adapter has been designed for vape tanks and rebuildable atomisers that have an 810 drip tip fitting. This adaptor allows you to use a 510 drip tip, instead of an 810 version. The benefits of a 510 are a tighter draw , which in turn boosts flavour and creates a slightly warmer vape . Always ensure you check compatibility before use. Contains: 810 to 510 and 510 to 810 Drip Tip Adapter.
