Guarantee an absolute weather-tight, factory-standard environmental block on your custom wiring assemblies with this genuine Yazaki 7157-3561-80 brown single wire seal (SWS). Belonging to the heavy-duty Yazaki 58 W-Type Sealed connection family, this premium silicone rubber wire seal is an essential component required to shield high-current automotive circuits from moisture ingress, dirt contamination, and corrosive atmospheric road spray.

This brown silicone seal is specifically engineered to accommodate wires with an outer insulation diameter of **2.0mm to 2.6mm** (typically paired with standard 2.0mm² thin-wall FLRY or automotive AVS cabling). It slides seamlessly onto the wire strand prior to terminal termination and seats flawlessly inside the rear sealing cavities of Yazaki 58 W-Type connector blocks—most notably matching the popular **Yazaki 7223-1824-80 2-way brown fuel pump power plug housing** and its corresponding **7116-1233 2.8mm female crimp terminal contacts**. Replacing hardened or torn factory seals during loom overhauls is critical to prevent capillary moisture drawing into high-amperage lines.
