Propane Pigtail Connector Orifice Size?

I'm replacing the propane pigtail connectors, regulator and supply hose on my 68 Caravel.

I received two new propane pigtail connectors from Amazon. Type 1 ACME x 1/4" Inverted Male Flare, 12 inches long and rated at 200,000 btus per hour.

I noticed that the orifice size on the tank side on the new hoses is noticeably smaller than the orifices on pigtails that are currently on the tanks.

There were no orifice size options mentioned on the Amazon page.

Will this make a difference in performance/safety?

The important thing is the BTU/hour rating. That's a lot of BTUs at 200,000!

IMHO its probably plenty for an Airstream. The older pigtails probably had a bigger rating--and would (as much as I hate to say it) be massive overkill for an Airstream propane system...even running a generator is probably not that big a load.

The smaller orifice will probably limit the size of the leak if something breaks or gets disconnected. I would suspect the excess flow check valve would cut off sooner rather than later in case of a big leak in the case of the new pigtails.

Could you toss in a link for them--I'm getting ready to do some preventative maintenance of the propane system, and new pigtails and outlet hose are on the list in case I find brittle rubber....

This is the Amazon link for the smaller orifice pigtail. https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

I forgot to mention in my original post that the pigtails on my 2017 FB also have the large offices found on my 1968 Travel.
