These are good replacement flanges. I had no issues mixing and matching any of these parts with my spectra parts. The part that screws on the bottle seems to be a little shorter but it still works. Much better alternative to buying Spectra parts for twice the price. I mainly got this so I could deep clean the back flow valves and switch them out more often.
