12191818 GT 150 Female Terminal Socket

Delphi Aptiv 12191818 GT 150 Female Terminal Socket

The Component: Genuine Aptiv (formerly Delphi) 12191818 automotive sealed female socket crimp terminal contact. GT 150 Series / 1.5mm nominal blade width rating classification / Precision-formed high-conductivity copper alloy / High-durability Tin-plated finish / Reel Form & Loose Piece strip tracking / Component Alias Code: 12191818 / Global Order Reference: 12191818.

Applications & Fitment: Designed as a factory original equipment (OE) micro-precision terminal link engineered to preserve electrical pathway integrity across critical data lines. This 150-size female receptacle socket is a standard wiring harness staple across modern domestic, European, and marine electronic frameworks—most notably integrated throughout General Motors (GM) powertrain wiring configurations and industrial sensor harnesses. It serves as a definitive replacement crimp socket inside a wide variety of sealed environments, including under-hood oxygen (O2) sensors, mass airflow (MAF) sensors, manifold absolute pressure (MAP) sensors, and electronic throttle linkages. Unlike traditional terminals that use delicate exterior locking lances, this advanced tangless design features an internal retention mechanism, meaning the terminal relies entirely on the plastic locking finger inside the housing connector shell to click into place. Highly vulnerable to internal contact leaf spring crushing, core wing fracture, or alignment deformation if field technicians attempt diagnostic troubleshooting by forcefully jamming rigid multimeter probes into the small front mating face, or if wire crimping is performed with basic un-profiled hand tools rather than proper GT-series automotive die sets.
