Maymom 2X 11mm Two-Piece Wide Neck Flange Set for Spectra S1/S2 Pumps

Overview

Discover a thoughtfully designed two-piece flange set from Maymom built for Spectra S1/S2 pumps. This kit includes two 11 mm shields and two wide-mouth connectors, forming a complete flange assembly that supports double pumping. The 11 mm shield is sized for post-pump nipple diameter around 9–10 mm, helping to establish a comfortable seal during sessions. The two-piece construction emphasizes ease of assembly, disassembly, and thorough cleaning, and it pairs well with most hands-free pumping bras and DIY bra setups.
