Bakelite Washer for Electrical Insulation – M2 to M12 Sizes

High-Temperature Bakelite Insulating Washer – Precision Thermal & Electrical Protection (M2–M12)

Secure Your Components with Confidence – Insulate Against Heat & Voltage

When working with machinery, control panels, or custom equipment, one overlooked component can cause big problems. Our high-temperature bakelite insulating washers are designed for professionals who need reliable thermal and electrical protection—without overcomplicating the process.

Available in a wide range of sizes from M2 to M12, these washers help you prevent electrical shorts, absorb vibration, and maintain stability in high-heat environments. Whether you're assembling an industrial machine, modifying an appliance, or fabricating a control unit, this is the small part that protects your bigger system.

Built for High-Stakes Environments

You need more than a generic plastic washer. These bakelite-based washers are made from industrial-grade phenolic resin, trusted for its dimensional stability, heat resistance up to 150°C, and natural insulation properties. They're compact, lightweight, and easy to integrate into almost any setup.

What does that mean for you?
Fewer breakdowns. Safer systems. Less money wasted on replacements.
