Double O Ring 510 Drip tip?

[Amish3006]

Anyone know who sells the double o ring drip tips in the states? I've tried every drip tip I own in the top cap of my AGA T2 and they all wobble a wee bit. I've been looking and so far have only found sites in the UK, Philippines and Greece.

envision glass drip tips use 2 rings. Sorry don't know how to hyper link.

Let's resurrect this thread. There have got to be others out there that are tired of wobbly drip tips. Can anyone suggest a US vendor for one of the double o-ring tips?
