Yeah,

The OEM ones are quieter than the US one I put on my unit. But it's an apples-to-apples comparison, to me. I just wanted different threads.

The male-to-female fitting on the OEM one was a little delicate though, and I did accidentally break it off the OEM solenoid when removing it with a wrench, as I recall, but did solder it back together, even though it isn't actually in use anymore. So, be careful removing and reinstalling that gas fitting at the back.

Otherwise, here's a clip from Amazon, where solenoids are cheap and easy to find.
