1/2" MPT x Drip-Lock Adapter 67494

The stainless steel teeth really grip the tubing tight, and that rotatable O-ring makes lining up the threads a breeze instead of a wrestling match. I’ve used cheaper adapters that leaked at the seal, but this one held pressure right from the first turn-on and it’s been solid all week.

Finally a fitting that actually seals on the first try, that rotatable O-ring makes aligning the threads a breeze instead of a wrestling match. The stainless teeth grab the drip tubing firmly, and I had my whole manifold connected to the drip zones in under ten minutes.
