Product Overview

This series of grommets is injection-molded from high-quality, oil-resistant rubber. Designed to protect wire harnesses and cables passing through sheet metal, enclosures, or equipment walls, they prevent insulation damage from sharp edges and abrasion. They also provide waterproofing, dust protection, vibration damping, and electrical insulation. Widely used in automotive, construction machinery, and electrical equipment applications.

Key Features

• Multi-specification SupportCurrently supports multiple opening specifications, including round and custom cross-sections, to accommodate various cable size requirements:

  • Round opening: 40mm diameter, 60mm diameter

  • Irregular / Rounded corner opening: 76×46mm, 13×260mm, 13×370mm

• Excellent protection performanceMade of rubber for excellent elasticity and a snug fit, this seal effectively blocks dust and moisture from entering the wire pass-through. It also cushions vibrations and reduces friction between cables and metal components, extending the lifespan of the wiring harness.

• Easy to installFeatures a built-in flange for direct mounting into sheet metal cutouts, ensuring secure fixation without additional fasteners. Ideal for diverse installation scenarios with high assembly efficiency.

• Highly weather-resistantOil-resistant, aging-resistant, and capable of withstanding extreme temperatures. Designed for complex operating environments in vehicles and industrial equipment, it maintains integrity over long-term use without deforming or cracking.

Application Scenarios

Provides secure and reliable cable wall penetration protection for new energy vehicles, commercial vehicles, construction machinery, electrical control cabinets, and other equipment.
