1" Blu-Lock Coupling 31676

Water line was fixed and pressurized in under a minute with zero weeping at the joint. The rotatable seal is a game changer when you're working in tight valve boxes.

I tightened this coupling onto my drip line and turned the water on right away, not a single drop leaked. The stainless teeth grab hold firmly, and I love that you can rotate the connection after it's sealed.

I was honestly skeptical about an O-ring holding up under pressure, but this thing sealed on the first push and hasn't leaked a drop since I filled the line. Being able to pressurize the system immediately without waiting for glue or clamps saved me an entire afternoon.
