Varying flange sizes are available separately (15mm, 17mm, 19mm, 21mm, 24mm, 27mm, 30mm) to help you find your best fit as needs change.

Safety, care and storage

• All parts are BPA-free and compliant with FDA food-contact standards

Practical tips and usage scenarios

This kit is ideal for households that want a dependable, interchangeable option to refresh worn components or to support multiple pump setups. While not original Spectra parts, these components are designed to be compatible and interchangeable with Spectra S2, S1 and 9 Plus pumps, offering flexibility for everyday use. The mix-and-match approach can help you quickly reassemble your system after cleaning or travel, keeping downtime to a minimum.

Careful maintenance

To maintain performance, check seals regularly, rinse parts after pumping, and dry completely before reassembly. Keeping components clean and dry helps preserve suction efficiency and overall pump experience. Consider labeling parts by size and model to simplify future replacements and ensure you’re always using compatible pieces.
