If you run a Mimaki printer, having these ink tubes on hand is just smart planning. The 10-meter length gives you plenty of ink supply for multiple refills or different color changes. The 1.8mm x 3mm size works perfectly with Mimaki JV-3, JV-4, JV-22, JV-33, and JV-5 models - just make sure you're ordering the right diameter for your specific setup. What's cool is these tubes work with both solvent/eco solvent and water-based inks, so they're pretty versatile. The quality is consistent with OEM parts but at a much better price point. Installation is straightforward if you're familiar with your printer's ink system - just make sure to prime everything properly to avoid air bubbles. Ving has been making reliable printer parts for years, and these tubes have that same dependable quality. Much better than dealing with clogged lines or inconsistent ink flow from poorly made alternatives. Keep a few of these in your workshop so you're never stuck waiting for parts when you're in the middle of a big print job.
