The Agilent G4204-68712 is a genuine seal wash pump kit designed for installation or service of the seal wash system in the Agilent 1290 Infinity Quaternary Pump G4204A. The seal wash system continuously rinses the piston-seal area and helps reduce accumulation of mobile-phase residues, particularly when buffered or salt-containing eluents are used. The kit includes the peristaltic pump assembly, seal wash motor, housing, tubing, and installation hardware required to restore or add the seal wash function.

Seal Wash Function
The seal wash system circulates wash solution around the rear side of the high-pressure piston seals. This helps remove mobile-phase residues and minimizes deposits that can contribute to premature wear of seals and pistons.
For the G4204A quaternary pump, the seal wash motor connects to the module main board, and Agilent specifies this kit for service when the seal wash pump motor requires replacement.
