Yazaki 7158-3035 58/91 Series 9.5mm Single-Wire Silicone Cavity Seal

Isolate heavy-gauge power lines and safeguard high-amperage terminal grids against environmental degradation with the genuine Yazaki 7158-3035 single-wire cavity seal. Precision-molded in Japan by Yazaki to demanding original equipment standards, this high-performance silicone rubber grommet belongs to the heavy-duty 58 and 91 series infrastructure families. Engineered with a multi-tiered ribbed outer profile, it forms a high-compression, moisture-tight barrier within the connector cavity to deliver dependable IP67-rated protection against moisture ingress, high-pressure road spray, and engine bay fluids.

The 7158-3035 is engineered specifically for large-diameter automotive cabling with cross-sectional areas ranging from 5.0mm² to 8.0mm² (aligning with heavy-draw 10 to 8 AWG power lines). Optimized for large-format 9.5mm (.375) terminal systems, this resilient silicone seal is designed to be crimped directly onto the outer insulation jacket of the contact pin. It is heavily utilized across commercial freight platforms, automotive cooling systems, and specialized charging layouts to seal high-current connections feeding cabin blower motors, radiator fan assemblies, and primary auxiliary fuse blocks. This authentic replacement seal allows harness technicians to rebuild or service high-exposure power blocks with factory-grade reliability.
