Original t:slim and G4 cartridges

Hi all,

I’m one of those people who stockpile supplies, and must have missed the memo about Tandem changing their cartridge type. I went to order my “normal” 3 month supply, and the original t:slim 3ml cartridges are no longer available. The only ones Edgepark has are the G4 cartridges. Do these still work with the original t:slim pump? and the Inset infusion site tubing? They look the same, but I don’t want to spend $300 on supplies that won’t work, and I’m not eligible for the integrated pump until August.
I can’t find any info on the Tandem or Edgepark websites, only that they are compatible with the G5 integrated pumps.
Any help is appreciated, thank you!

The portion that changed is the connector that goes between the cartridge and the infusion set.
Previously Tandem was using the Luer lock connector.
Now they are using the t:lock connector.


Thank you! So I just have to make sure my infusion sites have the new connector this time.
