Everything needed to renew all the O-rings and deck screws to bring the Kayfun Prime back to new working order.
These are high quality nitrile by Svoemesto, not the cheap rubber found elsewhere, which are hardwearing and more suitable for eliquid use.
The kit represents excellent value as buying the items individually costs way more elsewhere.

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.
