Do you sell these kits without the adhesive lining?

At the moment we do not offer heat shrink tubing kits without adhesive lining.

Can a hair dryer be used to heat the tubes?

Thank you for your question. We recommend using a heat gun as a heat source.

what would be the correct size for 6242Y grade 2.5mm twin and earth cable? the cable measure 10mm x 5mm

If you are electrical engineer by trade your ansawer to your question should be why. Why are you using this shrink wrap on any type of twin & earth. If its been cut or broken then unless you have good knowledge of ac cabling and I presume you're competently qualified in this I would not suggest using it in any ac environment. By way of your disciption, if there is some kind of brake or join in two wires (cables) you would normally solder the joints and shrink wrap the joint to seal and secure. If in case of ac use only a joiner like waggo ect which is rated appropriately, if in doughty with any ac diy activity seek qualified abilities, you may only regret it soon or later if you don't. A bodge can kill😕🤔

Is this suitable for use in an aquarium?

It’s plastic so pretty inert. It depends on what you want to do with it.

would recommend these

a must to have on hand in the shop. Used for car wiring and to seal the ends with spade connectors to make a neat joint and protect the joint and reduce the chance of ingress. Also looks neater in engine bay - or wherever your using. Lots of different colours and size choice and inexpensive. Seal onto wire with a low flame on the blow lamp. But heat gun equally as good.

If you’ve already crimped you can put a larger tube over the connector and it will shrink enough

Great. Really shrinks all the way unlike another brand I have
