Grote 87215 Ultra-Seal G7 Straight-In 7-Way Plug & Receptacle, 24 in Harness

The Ultra-Seal G7 provides a sealed, serviceable 7-way power connection for heavy-duty tractor–trailer applications. This straight-in, flush-mount assembly meets SAE J560b and features a replaceable die-cast receptacle with solid brass pins, a recessed mount to repel water, and a thicker, harder-durometer spacer that maintains clamp load without deforming.

• Three-piece Ultra-Seal G7 design creates a sealed connection to reduce moisture intrusion and corrosion.
• Straight-in, flush-mount configuration fits tight mounting spaces to simplify installation.
• Receptacle is recessed into the mounting spacer to shed water and improve environmental protection.
• Thicker, harder-durometer spacer resists deformation under torque to maintain consistent sealing pressure.
• Replaceable die-cast zinc receptacle with solid brass pins allows service without rewiring to reduce downtime.
• 24-inch sealed harness provides reach and strain relief to speed replacements and repairs.
• Two alignment pins guide the plug into position to improve terminal engagement.
• SAE J560b compliance matches standard North American 7-way trailer connections to ensure compatibility.
