Raindrip 303G00UB 1/2-Inch Compression Hose End Cap Plug, fits 1/2-Inch Tubing or Dripline with 0.620 inch OD, Drip Irrigation, Black

These end caps have proven to be indispensable in uncapping end lines in an irrigation system when blowing out the system to clear out the water for winterization. We use a RainBird irrigation system for watering 20 large urns in a courtyard and these end caps are so easy to just be able to unscrew the cap when we need to open up the lines and blow out the water in the tubing in order to best winterize the system. While it takes very strong effort to slip the piece onto the end of the tubing, we have found they stay in place and do not allow leakage…w replaced all of the figure eight end caps used during the initial system installation. Warning the tubing to allow it to be more malleable prior to installation definitely helps you to be able to more easily slide the cap down over the end of the tubing…make sure you have squarely and evenly cut off the end of the tubing and you can allow the sun to heat up the tubing or in our case, we heat a clay bead filled medical wrap in the microwave and hold it on the end of the tube for a faster warm up. These end caps are a quality product and the one we chose after trying 2 other brands.

Finally, the correct end cap to fit our 1/2" irrigation tubing! Home Depot failed me twice and insisted that what I was purchasing was "exactly" the same as the failed Rainbird part that I had brought in. Both times, those end caps blew right off of the tubing. They didn't match exactly, even from a visual standpoint, as the failed Rainbird part I had in my hands had a green ring around the bottom, and the ones they sold me at Home Depot had a black ring or a blue ring around the bottom. After some research, I discovered that 1/2" tubing doesn't always have the same external diameter, depending on the manufacturer. I came to Amazon, and found the EXACT part, down to the color of the ring at the bottom, and these fit perfectly with no blow outs and no leakage. Hooray!!!! Our smart watering system is functional again, and we don't have to go stand out in the yard and water vegetation. I need to order more of these to have on hand when the older end caps continue to fail and leak, so we can replace them.

It takes a bit of force to get this fitting on the irrigation hose, but it's a very solid piece and seals really well.

This worked perfectly. It was the exact product I needed to cap a 1/2 inch irrigation line.

Not compatible with my 1/2” flexible irrigation tubing. May work with the cheaper rigid 1/2” tubing (which leaked like a sieve with the rain bird puncture connectors). I had to switch to compression style flexible 1/2” tubing with 1/4” compression style connectors for the 1/4” tubing. No more leaks very easy to install however, this end cap blew off when water turned on. Ordered a compression style end cap (screws on) and problem resolved. Other than the $$ wasted on the rigid pipe and fittings.

I like the design unfortunately the tubing has.1/2 id and this didn’t work for me.

I used these on my 1/2in drip lines installation 3 years back and they're holding up fine. You just push them in while twisting and they fit tight. You can twist them back out at the end of the season to flush out the water before winter, put them back and you're good for Spring. That said, I didnt drain the system this past winter and they held up.

Works great. Used to close hose opening in garage.

J’étais craintif mais il fonctionne très bien. Facile à installer.

Worked well and affordable
