Pump parts

Pumping accessories with silicone or glass where they touch milk, rather than conventional plastic.

Each accessory needs to fit the specific pump or feeding setup.  We identify compatibility and assess the parts that touch milk, without implying that one silicone replacement makes an entire pump plastic-free.  Follow the manufacturer's cleaning and replacement instructions for the complete system.

Maymom Silicone Backflow-Protector Membranes for Spectra S1/S2/9 Plus — 4-Pack Maymom Silicone Backflow-Protector Membranes for Spectra S1/S2/9 Plus — 4-Pack SILICONE Why we recommend it: Replacing just the silicone membrane lets you maintain a compatible backflow protector without discarding its outer casing.  This Taiwan-made four-pack fits current-style Spectra S1, S2 and 9 Plus protectors, as well as the listed Maymom protectors.  It does not fit Spectra’s older flat-style protector.  The rigid housings and pump are not included. Materials: silicone $8.99★ 4.8 · 1,000+ ratings View on Amazon
Medela White Silicone Replacement Membranes — 6-Pack Medela White Silicone Replacement Membranes — 6-Pack SILICONE Why we recommend it: These silicone membranes let you replace a worn valve flap without buying a whole new pumping kit.  They are genuine Medela parts for compatible older pump assemblies, including the Pump in Style Advanced.  Check that each membrane lies flat and seals properly; discard damaged parts instead of trimming them to fit.  They do not fit Pump in Style MaxFlow, Freestyle Flex, Swing Maxi or Sonata. Materials: silicone $6.64★ 4.8 · 6,000+ ratings View on Amazon
Nenesupply Silicone Duckbill Valves for Lansinoh — 4-Pack Nenesupply Silicone Duckbill Valves for Lansinoh — 4-Pack SILICONE Why we recommend it: These one-piece silicone valves let you replace a worn milk-contact part without buying a whole pump kit.  Their extended bases give you something to grip during removal, rather than pulling on the delicate tips.  This four-pack fits the listed Lansinoh Signature Pro, Smartpump and Manual pumps—not the Handsfree model—and is made by Nenesupply, not Lansinoh. Materials: silicone $8.99★ 4.8 · 3,000+ ratings View on Amazon

Maymom Silicone Duckbill Valves for Lansinoh Pumps — 4-Pack Maymom Silicone Duckbill Valves for Lansinoh Pumps — 4-Pack SILICONE Why we recommend it: These one-piece silicone valves replace worn duckbills on Lansinoh Signature Pro, Smartpump and compatible manual pumps.  The flexible milk-contact part is silicone, with no separate hard-plastic valve body.  Four replacements are included.  Wash gently without pushing a brush or other object through the slit, and replace a valve if it tears or no longer seals.  Made in Taiwan; this part does not change the materials elsewhere in your pump. Materials: silicone $8.99★ 4.7 · 2,000+ ratings View on Amazon
Maymom Silicone O-Rings and Membranes for Medela Harmony — 6-Piece Set Maymom Silicone O-Rings and Membranes for Medela Harmony — 6-Piece Set SILICONE Why we recommend it: This silicone set supplies four replacement O-rings and two valve membranes for a Medela Harmony manual pump.  Replacing a worn seal lets you keep using the pump rather than replace the entire assembly.  The small parts are silicone; the pump, valve bodies and bottle are not included.  Made in Taiwan.  Check your pump’s part layout before ordering and keep these small pieces away from children. Materials: silicone $6.99★ 4.7 · 1,000+ ratings View on Amazon
Nenesupply Silicone Backflow Membranes for Spectra — 4-Pack Nenesupply Silicone Backflow Membranes for Spectra — 4-Pack SILICONE Why we recommend it: These silicone membranes replace the flexible barrier that helps keep milk out of a pump’s air tubing.  The four-pack fits Spectra S1, S2 and 9 Plus backflow protectors, so a worn membrane can be replaced without discarding the housing.  Made in Taiwan by Nenesupply, not Spectra; the pack contains membranes only, not a complete pump or protector assembly. Materials: silicone $8.99★ 4.7 · 5,000+ ratings View on Amazon
Spectra Silicone Duckbill Replacement Valves — 2-Pack Spectra Silicone Duckbill Replacement Valves — 2-Pack SILICONE Why we recommend it: These one-piece silicone valves replace worn valves on compatible Spectra pumps without adding a rigid plastic valve body.  They detach for washing and help maintain the suction needed for milk collection.  The two-pack fits Spectra S1, S2, 9 Plus and SG pumps; other pump components may still contain plastic.  Replace damaged valves and follow Spectra’s cleaning directions. Materials: silicone $14.99★ 4.7 · 3,000+ ratings View on Amazon
Maymom Silicone Duckbill Valves for Ameda Purely Yours and Mya Joy — 4 Pack Maymom Silicone Duckbill Valves for Ameda Purely Yours and Mya Joy — 4 Pack SILICONE Why we recommend it: Semitransparent silicone makes it easier to see residue inside these replacement duckbill valves.  They fit Ameda Purely Yours and Mya Joy pumps, but not Mya or Mya Pro.  The four-piece set replaces the flexible milk-contact valves without adding a hard-plastic valve housing.  Made in Taiwan.  Keep brushes and other objects out of the slit when cleaning, and replace torn or worn valves. Materials: silicone $9.99★ 4.6 · 1,000+ ratings View on Amazon
Maymom Silicone Duckbill Valves for Freemie Closed-System Cups — 4-Pack Maymom Silicone Duckbill Valves for Freemie Closed-System Cups — 4-Pack SILICONE Why we recommend it: A torn duckbill valve can reduce pump suction or let milk back into the tubing.  These silicone replacements fit the specified Freemie closed-system cups, including Standard, SlimFit5 and SlimFit6.  Made in Taiwan.  They do not fit the older open-system cups, and some valve bases differ in size, so check fit before use.  Includes four valves, not the collection cups. Materials: silicone $14.99★ 4.6 · 1,000+ ratings View on Amazon
Nenesupply Silicone Duckbill Valves for Spectra Pumps — 5-Pack Nenesupply Silicone Duckbill Valves for Spectra Pumps — 5-Pack SILICONE Why we recommend it: These silicone duckbill valves replace worn valves on compatible Spectra pumps without a separate membrane to clean.  Nenesupply links this model to silicone that passed SGS food-contact extraction tests.  Some owners find the fit stiff; check your pump model before ordering.  We recommend these for the listed Spectra pumps, not as a Medela conversion. Materials: silicone $7.85★ 4.6 · 4,000+ ratings View on Amazon
Maymom Pull-Tab Silicone Duckbill Valves — Spectra-Compatible, 6-Pack Maymom Pull-Tab Silicone Duckbill Valves — Spectra-Compatible, 6-Pack SILICONE Why we recommend it: These silicone replacement valves have a pull tab that makes them easier to remove for washing without tugging on the delicate tip.  They fit the Spectra S1, S2, 9 Plus and Synergy Gold, among the pumps Maymom lists.  Check the exact model before ordering: these are aftermarket parts, not universal replacements, and worn or damaged valves can reduce suction. Materials: food-contact silicone $9.20★ 4.5 · 700+ ratings View on Amazon
Maymom Shorty Silicone Flange Inserts — 17 mm, 2-Pack Maymom Shorty Silicone Flange Inserts — 17 mm, 2-Pack SILICONE Why we recommend it: These silicone inserts reduce the nipple tunnel of a compatible 24 mm pump flange to 17 mm.  Their short design fits Elvie’s 24 mm shields and Medela PersonalFit Flex shields without trimming the insert.  Two are included, made in Taiwan.  Confirm both your flange size and pump model: this version does not fit Ameda Purely Yours or Mya Joy.  Other parts of the pump may still contain plastic. Materials: silicone $14.98★ 4.5 · 3,000+ ratings View on Amazon
Maymom Silicone Membranes for Legacy Medela Valve Assemblies — 8-Pack Maymom Silicone Membranes for Legacy Medela Valve Assemblies — 8-Pack SILICONE Why we recommend it: These small silicone disks replace worn membranes in compatible older Medela valve assemblies, so you can replace the flexible part rather than the entire kit.  This Taiwan-made eight-pack replaces membrane part 87088.  It is not for Pump in Style MaxFlow, Freestyle, Swing Maxi or newer Symphony kits; compare your valve assembly with the compatibility chart before ordering. Materials: silicone $5.99★ 4.5 · 700+ ratings View on Amazon
LacTeck 4th Generation BabyMotion Silicone Flanges — 12 mm Pair LacTeck 4th Generation BabyMotion Silicone Flanges — 12 mm Pair SILICONE Why we recommend it: These one-piece silicone flanges replace the rigid breast shields on a compatible pump, with a flexible window that moves during pumping.  The simple design comes apart from the pump for washing without a separate flange insert.  This price is for a 12 mm pair; check LacTeck’s sizing guide and your pump’s connector before ordering.  Other pump parts may still contain plastic.
