The Component: Genuine Yazaki 7158-3672-50. Automotive single wire cable moisture seal with rigid reinforcement ring (Pink Silicone / Grey Collar / Loose Piece).

Series Taxonomy: Yazaki YPT 9.5WP High-Current Sealed Series. A heavy-duty, ultra-robust Japanese automotive high-power interconnect platform engineered by Yazaki to deliver total environmental isolation and flawless voltage transmission across high-amperage vehicle circuit systems.

Terminal Interface: Dual-material composite profile engineered explicitly to wrap securely over large-diameter wire insulation jackets, locking firmly inside the oversized rear insulation crimp wings of heavy-duty YPT 9.5WP series terminals.

Locking and Sealing Security: Environmentally sealed to an IP67 rating with a robust continuous operating thermal threshold certified from -40 to +120 degrees Celsius. Utilizes an innovative, multi-ribbed pink silicone rubber body bonded directly to a rigid, grey glass-fiber reinforced PBT collar. This integrated composite ring provides crucial structural reinforcement at the rear cavity entrance, ensuring the thick wire insulation cannot deform or twist the sealing walls during high-force terminal insertion, maintaining a flawless moisture-tight barrier over long-duration vehicle deployment.

Mating Complement: Slides smoothly over the wire insulation before crimping, seating completely inside the large-gauge sealing cavities of both male and female YPT 9.5WP high-current connector blocks. Accommodates a large wire insulation outer diameter range from a minimum of 6.20mm up to a maximum of 7.30mm.

Common Applications: Extensively specified across prominent global passenger car, hybrid/electric vehicle (EV), and heavy commercial fleet networks, most notably within Toyota, Lexus, Hino, and Nissan platforms. Most frequently deployed inside high-current vehicle networks, including auxiliary cabin heater lines, high-amperage alternator charging feeds, main battery distribution loops, and primary fuse relay junction links. Highly vulnerable to tearing, severe compression taking, or ring separation if forced with uncalibrated tools or pulled during aggressive harness disassembly overhauls.

Yazaki 7158-3672-50 YPT 9.5WP Series High-Current Composite Single Wire Seal Pink/Grey

Re-establish an absolute, impenetrable environmental barrier at your high-power terminal entry paths and eliminate dangerous moisture tracking with the genuine Yazaki 7158-3672-50 high-current single wire cable seal. Precision-molded to strict Tier-1 original equipment global engineering guidelines by Yazaki, this heavy-gauge 9.5mm class composite cable isolator is an indispensable component for executing safe, long-term high-amperage automotive harness repairs and custom heavy-duty wiring overhauls. Engineered explicitly around the robust YPT waterproof series parameters, it provides a secure, gas-tight environmental seal that completely isolates vulnerable core copper strands from moisture tracking and localized resistance spikes.

The 7158-3672-50 seal stands apart due to its advanced dual-material construction, pairing a premium, highly flexible pink silicone rubber sealing body with a rigid, grey glass-reinforced Polybutylene Terephthalate (PBT-GF) collar track. This composite profile ensures outstanding structural tracking defense, superb dimensional stability, and absolute immunity to automotive fluid degradation from engine oils, battery acids, and environmental salt spray. When compressed inside the matching housing cavity, the multi-tier outer ribs deform uniformly to lock out road spray, ambient grime, and abrasive dirt. This authentic component allows independent auto-electrical trade specialists, fleet service hubs, and custom commercial vehicle modifiers to deliver reliable, factory-correct wiring restorations.
