[C3] 3.5mm OD T Splitter Connector Fitting for White Ink Tubes - 2.5mm ID

Worked perfectly! The Cartridge chip for the WF7840 was exact replacement and work flawless. Thank you for the quick ship.

Excellent Product. I wish I would have found this little pump a long time ago as this is a miracle worker on getting that capping station so clean. This now keeps my printhead so much cleaner. I highly recommend.

Thanks to your YouTube instruction I was able to order the part and fix my 83 yr old sister's printer. I am an 80 yr old female and was thrilled that this part fixed her printer and saved her some money since she did not have to buy a new printer. I have never before tried to fix something like this. Needless to say, I was surprised it work so well.
