Sumitomo 6185-1169 RS Series 4-Way Sealed Female Automotive Plug Housing

Restore uncompromised data fidelity, zero-resistance loop continuity, and premium environmental defense to your vehicle's emissions and auxiliary lighting networks with the genuine Sumitomo 6185-1169 4-way female sealed connector plug. Precision-molded to strict Tier-1 original equipment automotive engineering parameters by Sumitomo Wiring Systems, this 4-pin inline receptacle belongs to the field-proven RS Series interconnect family. Engineered with an integrated high-compression silicone rubber face gasket and precise rear cable-entry paths, it establishes a tight, waterproof barrier that completely insulates low-voltage data loops from aggressive engine bay road spray, fuel vapor pooling, engine oil film, and salt fog contamination.

The 6185-1169 carrier block is injection-molded from a premium, heat-stabilized Polybutylene Terephthalate (PBT) substrate finished in an industrial black tone, ensuring high dimensional stability, structural rigidity, and resistance to thermal stress aging across a severe operational envelope. The internal 4-position cavity grid is engineered explicitly around a 2.3mm (.090) terminal footprint, accepting high-conductivity female socket contacts like the Sumitomo 8240-0264 series crimp pins. Connection safeguards are reinforced by a dual-action system: an integrated top mechanical thumb-latch arm that clicks audibly onto the mating header, paired with a front-inserting 6918-1776 secondary terminal position assurance (TPA) lock plate to completely eliminate contact backing under intense engine vibration. Extensively relied upon across Japanese wiring networks—most notably as the main replacement plug for Nissan 4-wire oxygen (O2) lambda sensors, windshield water jet motors, and factory fog light feeds—this authentic component allows auto-electrical specialists to execute clean, factory-grade harness pigtail restorations.
