45077361 - SMRZ Seal SAC Ink Weight Sensor Coupling

45077361 – Ink weight sensor coupling (Coupling, SMRZ Seal SAC) – EFI Vutek QS/GS

The 45077361 ink weight sensor coupling (SMRZ Seal SAC) is a component of the ink-consumption weighing and monitoring system of the EFI Vutek QS and GS large-format printers.

It ensures the tight mechanical junction between the ink weight sensor and the UV ink supply circuit, with an integrated SAC seal that prevents leaks under vibration or pressure changes. A worn coupling causes wrong ink readings and leaks.
