19mm Flange and Duckbill Valve Compatible with Spectra S1 S2 Breastpump Not Original S2 Accessories Not Original Spectra Replacement Duckbill Valve and Flange

I bought a full kit before, but it was really hard to fit and not very comfortable, so I decided to try this flange instead. Honestly, the quality is even better than the original one. The edges are smooth, the size fits perfectly, and most importantly, it’s comfortable to use. I don’t feel any pain at all. Plus, it’s HSA eligible, which is a nice bonus. really happy :)

Perfect and cost effective product to replace my spectra parts! I love that they have multiple different flange sizes! So far these have held up great after 10 months with the exception of replacing the duckbills when needed

I measured 13 mm on one side and 14 mm on the other, and the 15mm flanges work perfectly! No pain, and good value.

These fit my spectra pump perfectly ♥️

I wasn’t sure if it was worth buying a whole new flange and just keep using the removable sizing inserts. With two less things to clean, I would say pumping is less stressful. I use this with the Spectra bottles. Just be sure they are on tight! I had one incident where the bottle knocked out with a bunch of breastmilk, but I haven’t had any issues since.

The product was great in that all the parts were compatible with Spectra’s parts and they functioned properly, but the sizing chart in the images was a little hard to figure out and I bought the wrong size. And with pumping, it’s so important to get a good size. I would air on the side of going down rather than up if you’re in between. When I measure, I’m at a 15-16, so I looked at the chart and it said to go to 19mm which was slightly too big and cause led some pain. As far as other details go, the parts are easy to use, easy to clean, and store just like any other parts would. It was a little pricey in my opinion, but it’s still way cheaper than brand name parts. It’s just a shame that you have to kind of guess with sizes and try them all out in whatever range you’re in.

Works great with my spectra. Provided a comfortable fit

I’ve had these for a couple months now at least and they’re still holding up really well!

Flimsy with rough edges.

I bought this to use with my spectra breast pump and it fit perfectly! Been using this daily for months and still going strong. Highly recommend

Good quality flange, fits spectra perfectly but no valves despite clearly staying flanges + valves. Disappointing as now I'll have to order more.

I’ll be honest, at first I didn’t really like these flanges. I think it was just because they felt different to the usual flange I was used to, especially with the insert, so I wasn’t sure about them at first. I decided to give them another go though and honestly, they were actually really good! I’m not even sure why I didn’t like them the first time 😂 Once I tried them again, I found they worked really well and I had no issues. They fit my Spectra perfectly and are really handy if you’re looking for compatible flanges. Sometimes you just need to give something a second chance! Overall, I’m really happy with them. They work great with my Spectra and I’d definitely recommend them.

Bought these to replace my broken Spectra flange. It works ok, not the same as the original parts. It loosens from the bottle when in use and doesn't stay on properly when pumping.
