  • Product categoryReplacement Parts
  • 5 metre length gives ample routing flexibility for DIY CISS setups

  • Supplied as a complete kit for straightforward self-installation

Universal CISS Ink Tube Kit

The YINGHUA kit supplies five metres of 4 × 3 mm tubing arranged in four colour-coded lines for continuous ink supply systems. It suits DIY installers who are converting Epson, Canon, HP or Brother printers to bulk-feed reservoirs. The flexible pipeline replaces brittle factory tubes and keeps ink flowing during high-volume print runs. Builders needing pre-assembled cartridges or proprietary fittings should look elsewhere.

Thermals Noise and Power Draw

Passive fluid lines generate no heat, emit no noise and draw zero electrical power during operation. Ink viscosity and ambient temperature are the only factors affecting flow resistance. The tubing remains stable across normal office temperature ranges without softening or cracking. No active cooling or power budget is required for the kit itself.

Questions about this item

How do I install the 5 metre 4×3 mm CISS tubing into my continuous ink supply system?

Cut each of the four coloured lines to the exact length between the external ink tanks and the printer carriage, then push the 4 mm outer diameter firmly onto every tank outlet and printhead inlet until it seats fully; the common mistake is leaving a loose fit that draws air bubbles.

When should I replace the 4×3 mm CISS tubing in the kit?

Replace the tubing once it becomes discoloured, loses flexibility, or shows hairline cracks, because aged lines restrict ink flow and introduce air into the 4-line pipeline.
