Feelers 1/2" PT Outer Hex Male Threaded PPR Pipe Plug End Cap Garden Hose Water Tubing Stopper Prevent Leakage Choke Fitting, Pack of 5, White

I had ordered some brass ones that claimed to be the right size and the leak still kept dripping. But one of these fit exactly, perfectly right. The tolerances were really nice. And the leak. stopped.

ok

Works as advertised. But make sure you get it ALL the way in to stop the water flow. The problem is - I don't know why you'd ever need 5 of them. But, the don't sell them by one or two for a reasonable price. Is what it is ...

My rain barrel came with an adaptor that leaked unless I sealed it shut with silicone, not vey useful when it came time to empty it to move. I decided to just complete replace it and these worked perfectly, plus I have extra incase the elements degrade it as it did with previous parts.

Bought these to try and replace a missing threaded plug to attach a Droll Yankee feeder tray to a Droll Yankee hanging feeder. The 1/2 inch plug was a perfect fit! Works on all three of my DY feeders.
