Yazaki 7158-3034-50 YPT 9.5 Series 3.4mm to 4.4mm Cavity Seal (Red)

Single Wire Seal (SWS)

Yazaki 7158-3034-50 YPT 9.5 Series Single-Wire Silicone Cavity Seal

Isolate heavy-duty power distribution lines and seal high-amperage contact grids against moisture entry with the genuine Yazaki 7158-3034-50 single-wire cavity seal. Precision-molded to strict Tier-1 automotive engineering metrics, this high-flexibility silicone rubber grommet belongs to the specialized YPT (Yazaki Power Terminal) 9.5mm high-performance interconnect family. Featuring a high-compression multi-ribbed external body structure, it creates a tight environmental block within the housing cavity to maintain an IP67 rating against fluid contamination, oil exposure, and severe high-pressure under-hood washdowns.

The 7158-3034-50 variant features a vibrant red color-coding profile for quick inspection alignment. It is specifically engineered to accept a tight wire insulation jacket diameter spanning 3.4mm to 4.4mm, frequently applied over highly flexible power conductors. Optimized for large-format 9.5mm (.375) heavy-current connector assemblies, this seal crimps directly onto the terminal wire wings to safeguard high-load nodes. It is widely relied upon to isolate heavy powertrain sub-circuits, including electric power steering (EPS) nodes, massive radiator cooling fan arrays, and main battery junction looms. This replacement component allows master workshops and commercial loom fabricators to achieve factory-grade environmental sealing during repair overlays.
