The Tape Coupler is used to connect two sections of drip tape together. Always keep a few extra couplers on hand in case repairs need to be made.
Color may vary.
The loc nuts have the tendency to push the drip tape off the barb.
It does work if you get everything just right.
The drip tape needs a clean square cut so once over the barb it can seat against the shoulder of the coupler and at the same time tightening the loc nut which is trying to force the drip tape off the barb.
If your hands are wet/dirty it can be a challenge.
It’s good to have just one fitting and no removable parts to loose.
I have to wonder if the loc nuts were removable and had right hand threads to assist the tape seating against the shoulder while locking the drip tape in place, would this be a better option?
If the drip tape was thicker it may work even better.
Over all it works with effort.
