High Pressure LP Regulator

I have 2019 Redwood 3881ES. On the curb side, the regulator is leaking.
This is a single stage 30 PSI high pressure regulator. Turns out that the threads on the regular are non standard (The OUT side) and I cannot find any replacement part.

Does anyone know what is the thread size and where can I get a replacement part (Keystone service sends me to a dealer. I called a few but they are not sure what regulator it is).

Thanks for your help

Ours was leaking a number of years ago and just found a straight fitting to replace it. Now that's not to say the RW hasn't done something stupid and added some unknown size fitting.
Yes I know it's suppose to be a safety feature, but with the new tanks if you spring a major leak they will shut off the flow. So my opinion is it's just a left over from the early days.

Take the old regulator to a local LP distributor, they should able to get you the fittings & the regulator, most likely cheaper than any rv parts shop or dealer.

Our original regulator developed a pinhole leak in the diaphragm. So I replaced it and several years later the new regulator started leaking. I then removed the regulator from the lines and connected the pigtail from the bottle directly to the hose that crosses over to the two stage regulator, using a coupling that I acquired at an ace hardware store.

That regulator is a safety requirement to keep all lines low pressure crossing a living area.
That line crossing from the curbside is now 200-250psi rather than 30. Are you absolutely sure that rubber line running across is rated for the increased pressure? I'd bet it's rated for little more than the 30 lbs it was put in place to handle.
If it were me I'd be putting that small regulator back in place & not recommend removing it to others. If that's your choice then so be it, but to recommend or suggest it's removal is irresponsible & dangerous.

I had to replace that regulator once on our Redwood. Prior to the Redwood we had a 2010 Palomino Sabre and it did not have that regulator on the crossover line because the line was rigid pipe not a rubber line. Just an observation.

Regulator

I just replaced mine on a 2013 31sl. It only took a few minutes.
You can get the exact replacement from Amazon.

Problem solved

I ended up buying a new regulator and that fixed the issue.
This is the product I used:

JR Products 07-30325 High Pressure Regulator https://www.amazon.com/dp/B00RCUXEUY/ref=cm_sw_r_apan_glt_fabc_EJWDW50W3RK9WZ1PSTTF?_en coding=UTF8&psc=1

Thank you so much for your help and advice
