Review on 💧 Superior Loc Line Coolant Component: Acetal Copolymer for Efficient Cooling by Michael Schafer

I bought these to replace the plugs on the low point drains on our caravan. My back hurt crawling under the trailer and wrenches to unscrew the plugs. I was told the drains use 1/2 inch fittings. Now I can kneel down next to the trailer and reach out to open the valve and drain the water. Ideal! Quarter turn to open, quarter turn to close.
