Mini Smart Plug Outlet (2 Pack) Compatible with Amazon Alexa Google Home IFTTT, no Hub Required, ETL and FCC listed Wifi enabled Remote Control Smart Socket by Refoss (Green)

This has a nice assortment of sizes. I was able to use several in faucets over 75 tears old.

Good assortment, reasonably priced

Pretty much a generic O ring kit. Does what you need it with the various sizes. No complaints. I don't know about durability and longevity or stretch strength elasticity.
