1/2" MPT x Drip-Lock-sovitin 67494

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.
