The AU-VE-CO PRODUCTS BD77902 is a standard insulating bushing made from black nylon, sold in a pack of 50. These bushings are designed to protect wires, cables, and tubing from abrasion and damage at panel penetration points, grommets, and sharp-edged holes. The nylon construction provides electrical insulation and resists moisture, making them a practical choice for automotive and electrical installations. Each unit weighs approximately 0.01 pounds, keeping the overall pack light and easy to handle on the job.
These bushings are used wherever wires, cables, or tubing pass through sheet metal, panels, or bulkheads that could cut or wear through insulation over time. Common applications include automotive harness routing, trailer wiring, electrical enclosures, and light industrial equipment. They are well-suited for technicians who need a reliable, off-the-shelf insulating solution in volume quantities for fleet, production, or service work.
Designed as an OEM-style replacement and standard fitment insulating bushing for automotive wiring harness and cable protection applications.
Typically installed by automotive technicians or electricians during harness routing or panel wiring. Power down or disconnect the battery before routing or securing wiring through any panel. Ensure the hole diameter matches the bushing outside diameter before seating to achieve proper retention and protection. Do not force an oversized bushing into an undersized hole, as this can compromise the protective seal around the cable or wire.
