I bought these items to replace the original tubing and duckbill valves on my Spectra S2. They both fit well and are easy to connect to the flange/pump and easy to remove. I like that the tubing is longer than the original ones. I have also purchased extra flanges and storage bottles from Nenesupply and have been happy with those purchases.
