Feelers 3/4" PT Outer Hex Male Threaded PPR Pipe Plug End Cap with Teflon Tape Garden Hose Water Tubing Stopper Prevent Leakage Choke Fitting, Pack of 6, Green

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.

Tends to loose up

They replaced a leaking cracked one I had previously. So they worked for me.

Perfect fit for the pvc pipe tee that holds the flow switch for pool salt cell when you remove it for winterizing.

The thread is correct to fit the female end of a garden hose, but the hose connector is not deep enough for these to work as is--The washer in the hose end collides with the washer on this device. You could remove the hose washer, or remove the one on this device; in the latter case the two will mate if the hose has an o-ring washer but not if it has a flat washer. In either case of removing washers, I don't know how good a seal you get. In my case I don't need a pressure seal; I am just plugging the ends to keep out contamination during winter storage.

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.

Did not work!

I bought these because I was tired of slugs being in the lines. They clog small holes up like sprinklers and hand held sprayers and are hard to clean. Using these over the winter or anytime you disconnect your hose and nothing crawls in. They seal well. Easy to turn. Close to the color of grass so they at least fit the look better than yellow.
