Hi,
We're glad to help! The CE4/Vision style Clearomizer - 510 Drip Tip Adapter screws into your clearomizer, allowing you to use 510 drip tips, which pop in (they do not thread) and are secured with O-rings. If this is the style of drip tip you are attempting to use with your clearomizers, then the CE4/Vision style Clearomizer - 510 Drip Tip Adapter is what you're looking for!
Best regards,
Brad
