✅ Warranty-Friendly – Color Matters

We handpick each tube to make sure the tubes are not stained. This distinction is important for maintaining eligibility under Epson’s warranty policies.

In some cases, customers have reported that Epson questioned their warranty claim due to the color of the ink tubes, mistaking them as stained or non-genuine. However, we've seen tubings that are stained by Epson's ink too. Our tubing comes from OEM sources and preserves that factory-original appearance. So you will not have a problem with Epson's warranty department.

Here’s a real-world example from one of our customers who only used Epson's genuine 522 inks but still get her warranty rejected:

“Hi Kevin. I’ve seen many of your videos. My Epson 3803 stopped working, and Epson diagnosed it as a hardware failure. They asked for pictures of my ink tank and rubber lines. After reviewing my photos, they claimed my warranty was void because the tubes were colored and not white. I explained they came colored from Epson. They insisted Epson only uses white lines. I’ve seen your videos showing colored rubber tubes just like mine. Can you help me prove to Epson that this is OEM?”

If you’re replacing ink lines and want to avoid unnecessary warranty complications, this tubing will help your printer look authentic and unmodified, just as Epson intended.
