The double barb really grips the tubing—I yanked on a connection and it didn't budge, which is exactly what I need for my drip lines. These tees fit my 1/4" soaker tubing perfectly and work with any brand I've tried so far.
These tees are perfect for when I need to split my 1/4" line off to a few different soaker hoses in the garden. The double barb really does hold the tubing firmly, and I haven't had to fight a single one to get it to seat right.
Fixing a leak in my soaker line took five minutes once these arrived—the double barb grips so tight I didn't even bother with clamps. All 25 tees in the pack had clean, consistent openings, and they pushed onto the tubing without splitting it.
