Sumitomo 6188-4776 4-Way Sealed Male Connector 1.0mm HVG

The Component: Genuine Sumitomo OEM 4-position high-density sealed male tab inline housing / Premium Sumitomo HV/HVG Sealed Series waterproof wire-to-wire connector plug / 4-way single-row inline matrix configuration / Pre-fitted with an integrated front-loading terminal position assurance (TPA) secondary locking retainer wedge / Outer body-molded locking ramp and slide-on mounting bracket track / Molded from premium, impact-resistant, heat-stabilized glass-reinforced PBT (Polybutylene Terephthalate) / Component Part Number: 6188-4776 / Alternate Engineering Identifier: 61884776.

Applications & Fitment: Highly reliable, waterproof, and dust-proof electrical wire-to-wire interface engineered specifically for delicate low-level signal and power circuits on Japanese automotive platforms—extensively utilized by Toyota, Lexus, Subaru, and Mazda. This authentic 4-pin 1.0mm (040) Sumitomo male housing block is a factory standard for under-hood and chassis wiring systems, regularly specified for oxygen sensors (O2), exhaust gas temp sensors, knock sensors, compact auxiliary lighting assemblies, and small-envelope solenoid drives. Designed to withstand harsh road spray, high-pressure engine bay washing, and continuous drivetrain vibrations, its durable PBT shell ensures a rigid structural interface. Once the 1.0mm male crimp tabs and individual wire seals are fully pushed into the rear cavities, the front-loading TPA retainer locks the contacts firmly in position, preventing terminal back-out. A key stocking item for professional wire-harness manufacturers, motorsport loom retrofits, and automotive trade wholesale supplies.
