White Silicone Rubber Cable Grommet — Open-Center Wire Protection Bush, 5–201.5 mm

Cables and wires passing through unprotected panel holes are exposed to sharp metal edges that cut insulation, cause shorts, and create safety hazards over time. This silicone rubber cable grommet seats into the panel hole and creates a smooth, rounded channel that protects the cable from the panel edge on both sides—eliminating abrasion, cuts, and metal-to-wire contact at the pass-through point.

Made from food-grade silicone rubber, the grommet is tough, flexible, and resistant to high temperatures, corrosion, and weather. Each size is specified by two dimensions: A (the panel hole outer diameter the grommet fits into) and E (the inner opening diameter the cable passes through). Available in 25 sizes from A=5 mm (E=3 mm) to A=29 mm (E=19 mm), with the full range extending to 201.5 mm. Color: white.

Size selection: Match dimension A to your panel hole diameter. Dimension E is the inner opening—select a size where E is close to your cable or wire bundle outer diameter for a snug, protected fit. If your cable is between two E sizes, size up so the cable passes through without forcing.

✅ Panel hole sizes (A): 5 mm to 201.5 mm — cable opening sizes (E): 3 mm to 19 mm (shown variants) — fits metal, plastic, and wood panels — open-center design for cable pass-through

✅ Key Features of This White Silicone Cable Grommet

🛡️ Cable & Wire Edge Protection: The grommet seats into the panel hole and covers the sharp metal edge on both sides—prevents insulation abrasion, cuts, and shorts caused by direct cable-to-panel-edge contact at the pass-through point.
🧲 Food-Grade Silicone Rubber: High-quality, food-safe silicone—tough, flexible, and suitable for electrical, industrial, laboratory, and food processing environments. White color suits clean-room and food-contact applications.
🌡️ High Temperature & Corrosion Resistant: Silicone rubber withstands high temperatures and resists corrosion, chemicals, and weather—maintains its protective function in engine bays, outdoor enclosures, and industrial environments.
⚡ Electrical Insulation: Silicone is a non-conductive material—the grommet insulates the cable from the metal panel edge, reducing the risk of shorts and electrical faults at the pass-through point.
📐 Dual-Dimension Sizing (A & E): Each variant specifies both the panel hole diameter (A) and the cable opening diameter (E)—select the size that matches your hole and cable dimensions for a precise, protective fit.
🔧 Press-Fit Installation: Push the grommet into the panel hole by hand until the flange seats flush against both sides of the panel. Thread the cable through the inner opening. No tools or adhesive required.

🎯 Who Is This For?

🚗 Automotive Wiring Harness Protection

Protect wiring harnesses passing through firewall, floor pan, and body panel holes—the silicone grommet eliminates metal-to-wire contact that causes insulation wear and electrical faults in automotive applications.

💻 Electrical Enclosures & Control Panels

Protect cables entering electrical enclosures, junction boxes, and control panels through knockout holes—the grommet seals the hole edge and prevents the cable insulation from being cut by the panel material.

🏠 Home Electrical & Furniture Cable Management

Protect cables passing through wooden furniture panels, desk grommets, and home electrical boxes—the white color blends with light-colored panels and the food-grade silicone is safe for home environments.

❓ Frequently Asked Questions

How do I read the A and E dimensions to select the right size?

Dimension A is the outer diameter of the grommet body—this must match your panel hole diameter. Dimension E is the inner opening diameter—this is the space the cable passes through. Measure your panel hole diameter and select the A size that matches. Then check that the E dimension is large enough for your cable or wire bundle to pass through comfortably. If your cable is slightly larger than E, size up to the next A/E combination.

Is this an open-center grommet or a solid blind plug?

This is an open-center grommet—it has an inner opening (dimension E) for cables and wires to pass through. It is designed for cable protection and wire pass-through applications. If you need to seal a hole completely with no cable opening, you would need a solid blind plug instead.

Will the grommet grip the cable to hold it in place?

The grommet primarily protects the cable from the panel edge—it does not clamp or lock the cable in position. If you need the cable to be held firmly in place, a cable gland with a compression seal would be more appropriate. The grommet allows the cable to move freely through the opening while protecting it from abrasion.

Can this grommet be used in outdoor or automotive environments?

Yes. Silicone rubber is weather-resistant, UV-stable, and handles the temperature range found in automotive and outdoor electrical enclosure applications. It will not harden, crack, or degrade from temperature cycling or moisture exposure under normal operating conditions.

How do I install the grommet?

Push the grommet into the panel hole from one side until the outer flange seats flush against the panel surface on both sides. The silicone body grips the hole wall by friction. Thread your cable through the inner opening (E). If the grommet is tight, apply a small amount of silicone lubricant to the outer body to ease installation.

Is the food-grade silicone safe for home and kitchen use?

Yes. Food-grade silicone is non-toxic and safe for use in home environments, including kitchen appliances and furniture. The white color is standard in food-contact and clean-room applications. It is suitable for protecting cables in kitchen equipment, home electrical panels, and furniture cable management systems.
