90 degree elbow at propane regulator

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

90 degree elbow at propane regulator

Would a longer pig tail do the trick?

Spec on that regulator says 3/8 flare outlet.
Did you remove the 3/8 flare fittings on outlet of regulator?

So one of my pigtails sprung a leak and as thinking about doing an elbow for the same reason but ended up just ordering longer pigtails.

All I could find was 1/4" inverted flare pigtails but my regulator and old pig tail had 3/8" connections... no adapter. Finally went to the RV store and bought the 3/8 - 1/4 inverted flare adapter. They didn't have an elbow with the same specs so I just decided it was better to keep some of my sanity and end my search there. Good luck to you!

Longer pigtail will have to be the answer.
The 3/8 outlet size is for the "outlet" side to the RV, not the inlet side (pigtails from the tanks).
Thanks for replies.

Beware of introducing more joints in gas lines. Each joint is a potential leak source.
I vote with just about everyone else, longer pigtails is a better solution.
