Tyre mobility kit

Pretty much every standard valve out there you can remove the core from it, I wouldn't worry.

Jimble - just looked at your initial link. This looks very similar to the Vauxhall kit (from the look of it, I would bet the compressor is made by the same manufacturer). The only difference is that the Vauxhall kit pumps through the cartridge whereas (from the photo) with the VW kit you look like you need to inject the sealant first, then inflate the tyre.

I had no issues with mine and you can even use the compressor for checking/inflating your tyres.

On the tyre valve core removal side of things, this... http://www.amazon.co.uk/Silverline-380159-Tyre-Valve-Remover/dp/B007OX3TYK/ref=sr_1_3?ie=UTF8&qid=1408802461&sr=8-3&keywords=tyre+valve+remover might be something good to have.
