This full set of replacement parts is compatible with the Spectra S1 PLUS, S1, S2 PLUS, S2 and 9PLUS breast pumps.
Spectra's Flange Replacement Set offers replacement parts for Spectra breast pumps. Remember to replace your breast pump parts every 3-6 months for optimal use.
Please note that if you need a smaller size flange, you can purchase a Spectra massager insert and it will bring your 24mm down to a 23mm size flange. If you purchase a 28mm and need a smaller size, you can purchase a massager insert and it will bring your 28mm down to a 27mm size flange. The Spectra massager insert does not fit 32mm flanges.
