About Product

Transform your Idaho Jones Pump-A-Wear wearable pump into a hands free collection cup. Attach the membrane cap where the motor usually goes and then connect the cups to your own breast pump tubing.

These membrane caps can also be used with some other wearable pumps. Please see Technical Details below for the full list.

If you already use Idaho Jones Pump-A-Collect Milk Collection Cups, these can serve as spare membrane caps so you are never without one.

How to Use

  1. If using it with wearable pumps, take off the pump motor. 
  2. Insert the membrane cap at the top, above the membranes.
  3. If your pump is compatible with the membrane caps directly (e.g. Spectra S1, S2, 9 Plus, Lansinoh, Ardo Calypso), then attach the tubing of your pump to the membrane cap and you are ready to pump.
  4. If your pump requires tubing adapters (e.g. Medela, Baby Buddha, Pumpables, Bella Baby), separately purchase tubing adapters to connect the membrane cap to your chosen pump.


Can I use these caps with any wearable pump?

They are compatible with many models but not all. Please refer back to Technical Details for a full list of compatible wearable pumps.

Do I need to buy tubing adapters?

Adapters are recommended for certain pumps, mainly those with plastic attachments at the end of their tubing such as Medela, Baby Buddha, Pumpables, Bella Baby). Please note that the tubing adapters are sold separately.

How to Clean

  • Cleaning: Hand wash with mild soap and warm water.
  • Drying: Air dry thoroughly before next use.
  • Storage: Store in a cool, dry place away from direct sunlight.


  • Heat Sensitivity: Do not boil or steam sterilize; it can deform the caps.
