What eco-lock fitting do I need to connect 3/4" eco-lock tubing to standard outdoor faucet? These adapters are too big. Inside measures 1-1/4" not 1".

This question is from 1 in. FPT x 3/4 in. Eco-Lock Adapter (5-Pack)

I am installing a hose-faucet watering system with the Eco-lock tubing and fittings and the Melnor 4-zone timer. I bought some of the Orbit 1 in. FPT x 3/4 in. Eco-Lock Adapters to connect the tubing to the Melnor controller. The outlets for the 4 zones are standard MPT that measure 1". Although the Orbit adapters have 1" FIPT printed on them, the inside diameter of the Female pipe threads measures 1-1/4" and therefore are too big for the standard male pipe threads on the faucet outlets of the controller. What Eco-lock fitting do I need to connect to the outdoor faucet?

Rated 1.0 out of 5 by 1 reviewer.
Rated 1.0 out of 5.0 by TOTAL FAIL Waited a week for these to come in because they aren't available in the store. When it came, it is 1" FPT x 3/4" Eco-lock. No, they didn't sent the wrong part number. The website description is not the same as the product. With winter coming in, we're set back another week on this project because the website and product are mismatched. October 3, 2015
