The GRACO 17A557 is a solenoid harness designed for use with MZLP (Multi-Zone Linear Pump) systems within the Therm-O-Flow (TOF) series. It is an electrical wiring assembly that connects solenoid components to the control system, ensuring reliable signal transmission and operation. The material is not specified in available documentation, but typical harnesses are constructed from insulated copper wiring with durable connectors. Its intended use is to facilitate the electrical control of solenoid valves in GRACO hot melt adhesive and sealant application equipment.
