Mack Multi-Purpose Insulator

Wondering how to insulate vibration or limit friction at critical touchpoints under your Mack vehicle’s frame? The Mack Multi-Purpose Insulator fits a variety of brackets, bushings, and mounting surfaces. These parts are often used around air tanks, crossmembers, or electrical junctions to keep them from rubbing metal-on-metal or transferring road shock into the body. Depending on the configuration, these insulators may also serve thermal or spacing purposes in tight locations. The Mack 20706143 is a good option during frame assembly or while working on undercarriage components where separation is needed.

Mack trucks are built to last, but when the time for repair and maintenance comes it’s strongly recommended to use genuine Mack® components. Designed and manufactured according to strict OEM specifications, Mack parts offer the same engineering and performance as their stock equivalent. This ensures a seamless fit, smooth installation, and reliable operation overall. Mack offers a wide range of genuine parts, including engine, exhaust, transmission, cab, and body parts and accessories. It also offers remanufactured components that offer the same good-as-new quality at a more accessible price range. All genuine Mack parts are tested in both the laboratory and field environments to ensure they meet or exceed industry standards.
