Rain Bird BC50/5PK Drip Irrigation 17mm Barbed Coupling Fitting, 5-Pack x 2

Arrived ahead of schedule. Well packaged. Was exactly what I ordered. It really IS a Rainbird product. RELIABLE SELLER!! THIS PHOTO: GOOD SELLER BROWN COUPLING ON LEFT, BAD SELLER BLACK COUPLING ON RIGHT. I ordered one earlier from another seller and the BLACK couplings were so small they would fall out of the half inch tubing.

Works as intended

These work great don’t buy the knockoffs like I did the first time you are asking for trouble.

I bought these couplings for repairing a cut in our Rainbird Copper Shield 1/2-inch diameter dripline. We also bought a coil of 1/2-diameter dripline. But that was still cheaper than the $!80 the sprinkler company would charge for a service call. We ran into a problem of lack of fit but did a successful work-around. The couplings were too large in diameter by the slightest fraction of an inch for the existing dripline. I called Rainbird customer service for help. They suggested that our installed dripline might be slightly smaller due to a difference in a manufacturing run--different dripline manufactured at different times might be slightly different in diameter. The helpful Rainbird customer service person suggested warming the ends of the dripline with a hair blow dryer and applying some dish soap to the dripiline to allow us to slip in the couplings. I held the blow dryer to one end of the dripline while my husband squeezed the coupling in. We used vegetable oil rather than dishsoap to make is slippery. I probably wouldn't have had the strength to push the coupling into the dripline. But my husband was able to. It worked!

Perfect for my sprinkler project!

As expected. Having the “push tool” helps.

Just what I needed. Worked well and easy to install. I used my heat gun to warm the hose ends since they were in the ground and it's not that warm early in the AM. No more leak. Quality product. Quick turnaround.

These barbed couplers are the greatest. They are exactly the same as the Rainbird branded couplers that are sold in the big box stores. And they are half the cost! They call the size 1/2 inch but that must be ID measure, but the distribution tubing is .700 OD measure. Using these barbed couplers to reconfigure my garden distribution size .700 OD tubing makes the job so easy now. I do use the Rainbird tool to insert them into the tubing. They are much easier to go on, fit very tight and they do not leak. So much better than the old style coupler that, depending on the wall thickness of the distribution tubing, were either impossible to get on or so loose they leaked. These couplers are water tight whether the tubing is thin or thick walled.
