Hey Cal, great question, and I’m glad you double checked on that.

I did confirm with Camco that the collar on part # CAM40055 is brass, so you’re getting a solid, durable connection there. That helps with longevity and gives you a more secure feel when tightening it down, without having to worry about cracking or wearing out like some plastic collars can over time.

What’s your water setup like, do you run a filter or softener before the regulator?
