I'm using it on some pieces from StevenLMZ79. Sticking the pure frontend without condom into the joint didnt deliver a perfect seal. May be cause the joint of Steven arent absolutely perfecty proceeded. But now its perfect!
I've paid 12 €, in the US the Sublimator Teflon Adapter costs around 10 $. The new adapter frontend from GHL will probably cost more. What for? You have to change the frontend too. More work, more costs problably no better fitting.
Yeah he has some nice pieces, though hit and miss for quality I guess. I have his 12" torus which is okay with the hopper, but I've been smoking out of it lately. Bit too big for vapour.
The normal mouthpiece in a 14mm female joint won't seal, unless the angle is right. As it is just one small ring that fits the joint as opposed to a proper 12-14.5 taper.
The new WPA will be longer, cooler and have better airflow. I plan on swapping my mouthpieces basically permanently.
The bonus is I can use my glass domes to extend the air path further, without any need for silicone without sacrificing the 100% seal
I'm getting a heady adapter made up that will work with all my glass and my EQ too.
I don't really have a go to set up that could use the Teflon otherwise it would probably be all the function I'd need. But I've been using oil rigs with male joints and they're all worth more than the hopper, so spending a little to optimise my hoppering is on the cards after a year of silicone use (I hate silicone on vapes, the EQ hose turned me off it)
The GH sleeves are decent quality. I had to replace one after my friend lost one, and when they're fresh they're great. After a year its congealed with plant oils and scuffed from use.
I have 2m of coloured silicone from seventh floor en route to keep my old mouthpieces and oil rigs happy too
