Push Fit 3/8" Tube X 9/16" Male UNEF - Black 3/8 Compression Adapter // GS3 braided line to 3/8 tubing fitting

Exactly what I needed to hook up my water line to my sink on my coffee cart.

If you're looking to hook up a pitcher rinser or sink faucet in a coffee cart, this is the piece you haven't been able to find at any hardware store, plumbing store, etc. It took me forever to realize that this was the one thing I was missing. If you're hooking up a Flojet (or similar), you'll bring the 1/4" tube to the 3/8" tube with another adapter piece, then the 3/8" tube to this so that it connects to the rinser/sink line. Don't hesitate - buy it now so you can finish your project sooner!

This works perfectly with my GS3 plumbed in. Thanks Caffewerks for the quick and easy recommendations.

After searching high and low to find an adapter for the water line on a La Marzocco GS3, this was the one part we needed to connect it to a pex water line for using with the Simple Cart System. Additionally, many RO water systems use pex tubing in this size, so going back and forth between portable cart mode and in-line water is a breeze.

I had such trouble finding a John Guest Push Fit accessory to fit my waterline connected to my La Marzocco Espresso Machine. After numerous emails and many purchases from other companies, I was super thankful for Zachary and his diligence in leading me directly to what I needed. Very pleased!
