The Component: Genuine Yazaki 7158-3167-80 individual automotive single-wire rubber cavity seal.

HS / RH Sealed Series 0.64mm (025) waterproof cable insulation seal (Brown-Red Variant / Silicone / Individual Piece.

Applications & Fitment: Designed as a primary factory original equipment (OE) harsh-environment moisture, dust, and splash barrier for low-voltage, high-density automotive sensor wiring harnesses. Universally specified across global passenger cars, commercial transport, and industrial instrumentation networks to seal the rear wire entries of Yazaki HS and RH series waterproof connector plugs. Highly vulnerable to mechanical tearing or rubber slicing if forced into compact housing cavities using un-profiled sharp hand tools, or structural degradation if exposed to prolonged chemical contaminants outside specified engine-bay limits.
