Spectra breast pump valves, membranes and tubing by part number

Spectra's replacement tubing comes as two silicone tubes with adaptors for the Dual series, and Spectra Australia says it suits any Spectra pump. Never wash or sterilise the tubing: it cannot dry properly inside. Spectra says to replace it if moisture or milk ever gets in, and when it is dirty or discoloured, or the ends stretch and slip off the pump too easily.

After the change: No reset: the pump has no reminder for this part, so set your own.

Fits 7 Spectra models: 9 Plus, Dew 350, Dual Compact, Dual S, M1, S1, S2.

Spectra's white silicone duck valve presses into the base of the breastshield on the S1, S2, 9 Plus, M1, Dew 350, Dual S and Dual Compact. Spectra's manuals say to replace it every 2 to 3 months, or when suction drops; Spectra Australia says regular pumpers often need one about every 3 months, sooner if pumping more than once a day. Dishwashers and frequent sterilising wear it faster. It does not fit the Handsfree Cups.

Change it every 2 months; 5 steps, no tools.

These are the silicone diaphragms inside Spectra's standard backflow protector, sold in pairs so you can refresh both sides without buying whole protectors. Spectra Australia says they stretch over time and should be replaced every 2 to 3 months if you pump once a day, or every 6 to 8 weeks if you pump more often. A torn or wet diaphragm can let moisture into the motor. They do not fit the Handsfree Cups.

The backflow protector sits between the breastshield and the tubing on Spectra's S1, S2, 9 Plus, M1 and Dual series pumps, keeping milk and moisture out of the tubing and motor. It is sold singly, so double pumpers need two. Spectra's manuals say to replace it every 3 to 6 months; Spectra Australia adds sooner if the silicone diaphragm inside is damaged. The diaphragm is also sold on its own.

Change it every 3 months; 5 steps, no tools.

This is the backflow protector for Spectra's Handsfree Shield Cups; it differs from the one on the standard breastshield. It is sold singly, so add two for double pumping. Spectra Australia says to replace it about every 3 months, or when the diaphragms inside look or feel floppy, or suction drops.

Change it every 3 months; 4 steps, no tools.

These smaller silicone valves are for Spectra's Handsfree Shield Cups, the in-bra cups that pair with any Spectra pump. They do not fit the standard wide-neck breastshields. Spectra Australia says the Handsfree Cup valves need replacing as often as the standard kit parts, which Spectra's manuals put at every 2 to 3 months for duck valves, or when suction drops.

Two replacement diaphragms for the backflow protector of the Spectra Wearable, the in-bra pump that collects milk straight into its own container. Spectra Australia sells them in pairs. Spectra gives no separate interval for the Wearable's parts; replace a diaphragm when it is torn or worn, or when suction drops.
