(5-Pack) 1/2″ Universal Nut-Lock Coupling Drip Irrigation Tubing Compression Fitting Connector (Fits All Tubing .530, .600 and .620 ID (16, 17, 18 mm) (Coupling 5-Pack)

I was about to return these because, like others, I could not get the brown nuts over the tubing to reach the threads of the main body. I was following the directions in the product listing. But then I realized the directions are wrong. Start with the nuts already threaded all the way onto the body. Then push the tubing onto the barbed end of the body. Finally, twist each nut to back it down onto the tubing. Easy enough, but not like the directions.
