Do these valves work with the 2 year old Avent twin electronic breast pump that originally came with the duckbill style valves?

NO. You will need a valve like the following listing Maymom Pump Valves for Philips AVENT ISIS Breast Pumps; Duckbills to Replace Philips AVENT Valves Used in Manual, Single Electric Breastpump and Twin Electric Breast Pumps Valves (aka Avent Duckbills or Philips Valves or Avent ISIS Valves); 4 Pieces in Retail Package (Factory Sealed).

I think these will only fit the Classic Avent bottles. My sister accidentally bought Natural nipples for her classic bottles, and they did not fit. So I would assume it is vice versa.

As far as I know yes..... I have a double pump that is about 4-5 years old and these were perfect for it. As far as any of the earlier models I wouldn't know though. Hope this helps!

Hmm... They should work but I had to buy the accessory kit which has yellow rings that they pop into. These worked with the 2oz pumping bottles and other 5-8 oz bottles, all of which I got at baby's r us.

Yes. That is one of the advantages of this pump. I used the same 30mm breast shields with the Harmony as I do on my Freestyle and they fit the same way they do on the electric pump.

They should...these are the same shields that come with the pump. I bought extra to have two sets.

I have both the Avent Classic and Avent Natural bottles; the systems work quite well together - sippy cup spouts, breast pump, and sealing discs fit well on both systems. Avent Classic has an extra ring in the assembly (on top of the bottle directly, before doing the screw-top portion with the nipple), which the Naturals seems to have integrated into the bottle itself.While I've not used THIS specific sippy spout, I've found everything I've used on one system can fit on the other. Including nipples and the rings -- you're not *supposed* to mix and match the nipples and bottles, but you can.

They are compatible with the Medela pumps but I'm not sure of the model you're asking about. I love the bottles!

I have the Ameda double pump, I wouldn't know about other models but, it works great on mine!!I can't imagine Ameda not making them universal.

No. These are for the electronic pump only. These are missing the attachment part needed for the manual pump. DO NOT GET THESE FOR THE MANUAL.

I really dont know, they fit exactly so it will be difficult to tell. Im very pleased with my pump, it works perfectly!!! I just LOVE IT!!!

These work with all pumps that use the standard bottle thread. All WHO compliant pumps must use this thread.

This pump only fits the newer wider-mouthed Avent bottles, not the standard ones. I didn't buy all new bottles, though. You can just transfer milk into your container of choice. I haven't ever used bottle liners--do you mean liners like the playtex drop-ins? I don't know how you'd attach them to this pump.

I bought a set of these (Gilmour) faucet quick releases. They work great with some of the older plastic releases that I have. I never considered compatability until I was asked this question. I just assumed that all manufacturers were interchangeable. So far I have no reason to believe other wise.

I do not know for sure because I haven't used the glass ones, but I would assume yes. I have been using Avent products since 2006 and they are all interchangeable...which is one of the reasons I bought these in the first place. These rings fit on my very old bottles as well as my new ones.
