Spectra® バックフロー プロテクターは、Spectra® S1、S2、9 Plus、Synergy Gold 搾乳器と互換性があり、各搾乳器に付属していた元のバックフロー プロテクターと交換できます。
特徴：
After my original protector got cloudy and started losing suction, this replacement snapped right in and my pump pulled like it was brand new again. It's a small part but the seal is tight and I haven't had a single drop sneak into the tubing since.
I was dreading replacing this little part, but it snapped into my S2 just like the original and the pump is working perfectly again. The fit is exactly what I needed to keep things running smoothly.
Finally found a replacement that fits my Spectra pump perfectly and it works exactly like the original. The seal is tight and I've had zero leaks since swapping it out a few weeks ago.
