I have such a cheap system for this, all you need is sealant, a brake bleed syringe with the plunger removed, and a valve remover and it works great:
* Leave wheel on bike. Situate value at the bottom.
* Remove valve core.
* Insert syringe body into valve body.
* Poor sealant into syringe body
* Gently squeeze and release tire to create suction
It's a slightly longer process than using a dedicated injector but I always use syringes that have died for their intended purpose of bleeding disc brakes so it costs nothing.
Wrenching on bikes I regularly use a Stan's injector with regular valves without issue but it's not something I'd bother buying for home.
