It is aimed at parents who need a complete spare set of parts and want reliable compatibility at a lower price than buying original-brand accessories. The single biggest reason to consider this kit is that it supplies a full set of commonly needed components - flanges, backflow protectors, tubing, duckbill valves and wide-neck bottles with a rewritable two-piece cap - so you can replace multiple wear items in one purchase.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull kit contents:\u003c\/strong\u003e Includes two 21mm flanges, two backflow protectors, two tubes, two duckbill valves and two wide-neck bottles with two-piece travel caps to cover both sides for most pumping sessions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpectra compatibility:\u003c\/strong\u003e Designed to be interchangeable with Spectra S1, S2 and 9+ parts so users can mix and match without modification.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaymom quality:\u003c\/strong\u003e Manufactured by Maymom LLC and inspected under US FDA registration and other international health authorities, which supports material safety and regulatory compliance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRewritable bottle cap:\u003c\/strong\u003e The two-piece cap has a writable surface for dates or baby names that can be erased with soapy water, easing storage and daycare labeling.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEasy cleaning:\u003c\/strong\u003e Parts are safe for boiling, steam sterilizers and microwave steam bags so they fit common cleaning routines.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThis kit is best for parents who already own a Spectra S1, S2 or 9+ breast pump and want a cost-effective set of spare or replacement parts that perform like OEM pieces.
