AL166181 Hydraulic Quick Coupler Socket | OEM Replacement for John Deere

AL166181 is a premium OEM-grade female hydraulic quick coupler socket built for John Deere farm tractors and agricultural machinery. Following ISO 7241-1A industrial standard, this heavy-duty quick disconnect fitting serves as a direct cross-replacement for multiple OEM part numbers including AL119348, AL200979 and 3CFPV. It effectively solves common hydraulic system faults such as oil leakage, pressure drop and poor connection caused by aging or damaged original couplers. Adopting self-sealing poppet valve structure, it ensures stable, low-spill and leak-free hydraulic transmission for daily farming, tillage and landscaping operations.
