I've been using this with a Tempest head on my rigs, and it works beautifully! I ordered 2 -- one as a backup -- and both have high-quality ground joints w/ zero wobble and a perfect seal. Shipping was super fast too, thanks Scott!

I’ve been using it with a Tempest head and it’s been working great. It’s long enough that it’s not too warm when grabbing it and doing reheats, yet short enough to not be awkwardly sticking out of my bubbler. Would buy again. My only knock is that the logo has started to come off after a couple iso soak cleanings. But that doesn’t bother me at all, so I still give it 5 stars.

Just what the doctor ordered for connecting an 8mm input device to a 14mm water/dry vape piece. It handles my Tempest and Dynavap just as expected!

Exactly what I was looking for! Great price too
