Bloco de engate hidráulico múltiplo John Deere AH166991

The AH166991 is a hydraulic multi-coupler block assembly designed as a single-point connection interface for John Deere combine header hydraulic systems. It integrates five quick-release couplers into a single mounting block to facilitate rapid header attachment and detachment. The block contains three 1/2 inch and two 3/8 inch male couplers with ORFS (O-Ring Face Seal) threads, color-coded for circuit identification. It mounts on the header front frame and engages with the combine female receptacle. This unit replaces OEM part numbers AH166991, LAN166991, X27551, AFH209071, AH208706, AH201340, and HXE117551. It is engineered for the hydraulic flow and pressure demands of John Deere 6068 series engines used in CWS and WTS combine models, as well as 600, 700, and 900 series cutting platforms.
