I have a model 6020 auto. change over regulator with two 12" hose's, one going to each tank. I wanted to reduce the bend in the hose by installing a 90 degree elbow coming out of each side of the regulator. My hoses have the 1/4" NPT end (not the inverted flare) that has a 20 pitch thread. I ordered a 1/4" NPT (male - female) 90 degree elbow from Amazon (Boeray 2pcs Brass Fitting, 90 Degree Barstock Street Elbow, 1/4" NPT Male Pipe to 1/4" NPT Female Pipe), but those threads are 18 pitch and a little larger in diameter and won't fit into the regulator. Researching, I can't figure out why the 2 different pitch and size for 1/4" NPT fittings.
So I'm asking here if anyone else has ran into this, and if you know where I can get a 20 pitch 1/4" NPT elbow.
Thanks,
Kevin
