Brennan Industries 6505-02-04 Steel Straight Tube Fitting, 1/8″-27 NPTF x 7/16″-20 SAE Thread, 1/4″ Male NPTF x 1/4″ Female JIC Swivel
If I’m reading these specifications correctly, I believe that this *may* fill in for the (often difficult to find) fitting featured in Style 1 of my Spunding Valve Build. A Spunding Valve allows you to ferment under pressure, naturally and precisely carbonate in the keg, fix over-carbonated beers and more.See: [Build a Spunding Valve]. I plan to order this fitting and give it a try.
