Anyone have one of these or have access to one they can purchase locally.
Online sources I've found want $8 or more for shipping.
Here's a pic:
About the only thing I can think of that I've seen in a hardware store would be two 1/4 MFL to 1/4 MIP adapters(brass) joined by a 1/4 coupling (also brass), but that may end up costing about as much as the part in your picture plus shipping.
I have an extra one sitting here at home. And I can buy more at the local hardware store. Shoot me a PM if interested.
