@ Anniepan: please, internal diameter? Does it fits YFTK or other SKUs?
Hallo, Anniepan/staff.

I would like to know the internal diameter of this top cap for Speed Revolution RDA.

You will probably know that not all the Speed Revolution styled RDAs have the same base diameter.

The YFTK SKU 7281800 (that is supposed to be an 1:1 replica) has different (smaller) base compared to the SKU 7531500

So, can you please check the top cap's internal diameter for me?

Thanks

I've measured the internal diameter of mine, it's 16.4 mm.

I'm using it on SKU 7441200

It will also fit tightly on the Speed Up SKU 9622950.

Hello MC202_FT,

The inner diameter of the cap is 16.5mm, the outer diameter of the cap is 18mm. The inner diameter of drip tip is 5.5mm, the outer diameter is 10mm. We will test it with YFTK SKU 7281800 and SKU 7531500, then update the news for you.

Good job, Anniepan and cmj55.
Fast and detailed answers, exacty what I needed.

Still, Anniepan, I remain somehow skeptic that the cap will fit both the SKUs.
I have just checked again and - on my RDAs, both from FT - the black cap from SKU 7531500 has a very loose fit on the YFTK base (will not seal, maybe not even using fatter o-rings) and the YFTK SKU 7281800 cap will not even enter on the black base being too small (there is a 0.5mm. difference, more or less, but - out of curiosity - I will recheck it properly with a caliper).
But, anyway, it doesn't matter: I have the actual PEI cap inner diameter, and the integral drip tip inner diameter too!
I am very happy!

Thank you so much, both of you. :-)
