These service kits have every single seal required (even the drip tip) to bring the Prime back to as new working condition and are made from a high quality material.

To make identifying where each seal should be fitted easier, I printed out an exploded diagram of the Prime showing all sizes and their positions which you can find with a quick browse on the web.
Lay them all out in size order so that you can identify and match each easier as the 11x1.5 and 10x1.5 are very similar when held up individually.

Smear a little VG or any eliquid on each seal as fitting and change all, regardless of their condition, the two in the top cap and also the two around the build deck are the most prone to wear but coating these 4 seals with VG (or just eliquid) after each re-wick extends their life.

For just a few coins these kits are exceptional value for money and will keep your Kayfun working at it's Prime for many years to come.

Fantastic I am very happy with my Purchase of the 3 sets Svoemesto Kayfun Spears Kit these O-rings and deck screw have transformed my 3 Kayfun Prime RTA's to brand new performance I am very grateful to Creme de Vape for stocking these extra products for Svoemesto Kayfun Prime these have been a life saver for my daily vaping favourite RTA Rebuildables and another massive thank you to Creme de Vape for the superb next day delivery service and the sweet treat.

I was having problems with leaking from the base of my Kayfun Prime RTA so I bought this kit and changed the appropriate O rings and now it’s as dry as a bone. I will always keep a spare set of these now just in case. Thank you Creme de Vape for stocking these Kayfun spares.
