Review on 200 Waterproof Heat Shrink Butt Connectors For Marine And Automotive Use - 16-14AWG Blue Wire Crimp Connectors by Ryo Flora

I used these to connect landscape lighting wires, Just to make sure, after crimping and heat shrinking. I sealed them with liquid tape just for good measure (probably a bit of overkill), but I never want to chase down another corroded wire that is buried underground. I really liked how these crimped and sealed.
