Ink Tube One-Way Valve 6x4mm
This transparent one-way valve connects 6 mm outer-diameter and 4 mm inner-diameter tubing in inkjet printer ink supply systems. It allows ink to flow in a single direction, preventing backflow and air bubbles during printing or maintenance. The clear housing lets users confirm fluid movement visually. Supplied as a single replacement part for compatible ink delivery setups.
For inkjet users maintaining a continuous ink supply
Suitable for technicians or owners who need to replace a worn or blocked valve in an existing 6x4 mm ink line. Buyers whose printers use a different tube diameter or connector style should look elsewhere. Not intended for pressurised systems outside standard inkjet ink delivery. No tools or additional fittings are included.
