HP Designjet 4000, 4500 Ink Tube System Ink Supply Valve (single)

Part number: C6074-60342-V (for tube systems Q1273-60050, Q1273-60300)

Rebuilt and upgraded ink supply valve assembly (single) for the ink tube system of HP Designjet 4000, 4020, 4500 and 4520 printers. Half of ink tube assembly failures are caused by leaking ink supply valve assemblies: the OEM synthetic rubber seals harden and crack over time, letting ink out and air in. The LPS valve assembly uses silicone seals that do not react with ink or oxygen, and every assembly is leak tested at twice normal operating pressure.
