502 Ink Refill Bottles Compatible with ET-2850 ET-3850 ET-15000 - High

Our review of the 502 Ink Refill Bottles finds them best suited for home offices and small businesses that need a low-cost, high-capacity ink solution for Epson ET-series printers. The single biggest reason to buy is the high page yield and easy refill design: the 502 black refill claims up to 8300 pages at 5% coverage, and the bottles use an auto-stop nozzle that makes refilling straightforward and clean compared with loose syringes or cartridges. For anyone running frequent monochrome or color print jobs this set delivers consistent output and strong color saturation without frequent cartridge swaps.

Key Features

• Wide compatibility: Designed to work with a long list of ET-series and ST-series printers, so you can replace or top up ink on many popular models without worry.
• High page yield: The black 502 refill offers a high capacity that reduces the frequency of replacements, which is useful for heavy text printing in home offices.
• Auto-stop nozzle: The special nozzle design prevents spills and drips, making refills easier and less messy than traditional bottle tops.
• Color performance: Formulated for high color saturation and sharp text, producing vibrant prints and consistent results across documents and photos.
• Complete kit: The set includes multiple bottles of each color so users get several refills in one purchase, lowering ongoing printing costs.

Who It's For

The 502 ink refill bottles are aimed at users of compatible ET and ST printers who print regularly and want lower cost per page than OEM cartridges. It is particularly well suited to home offices, students, and small businesses that need dependable black text output and occasional color prints without frequent cartridge replacements.

Users who want factory-brand ink with manufacturer support or those using non-listed printer models should look elsewhere. Also, extremely occasional printers who prefer OEM warranties and single-use cartridges may not benefit from the higher upfront bottle volumes.
