Straight Ink Tube Connector 6 mm to 4 mm is a replacement impressora ink line part for ink supply, circulation or maintenance systems. It is used in the ink path, so the correct tube size, connector direction and ink compatibility must be confirmed before installation.
Application reference: UV, eco-solvent, solvent and water-based ink line repair or extension where connector material is compatible. This is a generic ink line part, not a model-specific OEM part. Confirm by old tube, connector, pump or installed position antes de encomendar.

Measure the old tube inner diameter, outer diameter, wall thickness and connector barb size. Also confirm ink type, tube hardness, bending position, pump roller size if used in a pump, and whether the line carries positive pressure, negative pressure or waste ink.
Install with the ink path depressurized where required. After replacement, check for leakage, air bubbles, loose tube ends, flow restriction and chemical swelling before production printing.
Can I choose by impressora brand only?
No. Choose by tube size, connector type, ink type and installed position.
What should I send if unsure?
Send photos of the old tube or connector, measured inner / outer diameter, ink type and impressora model.
