Freightliner Columbia 112/120 Air Tank-Wrap-Mount

Frequently Asked Questions About Freightliner Columbia 112/120 Air Tank-Wrap-Mount

What exactly is an air tank wrap or mount used for?

Air tank wraps and mounts are the brackets and strap assemblies that secure your air brake system's air tanks to the truck's frame rail. They keep the tanks stable and properly positioned so the air system functions safely and the tanks don't shift or vibrate loose during operation.

Will this air tank wrap or mount fit my Freightliner Columbia 112 or 120?

Products in this category are designed specifically for Freightliner Columbia 112 and 120 model trucks, but frame configurations and tank sizes can vary by year and build. Always check the listed tank diameter, mounting hole spacing, and frame rail dimensions against your truck before ordering to confirm a proper fit.

What materials are these wraps and mounts made from, and how do they hold up over time?

Most air tank wraps and mounts are made from steel or aluminum, often with a protective finish such as powder coat, paint, or plating to resist rust and corrosion. Steel versions tend to offer more strength for heavier tanks, while aluminum options can help reduce overall weight. Look at the specific finish listed on each product page, since durability in road conditions like salt and moisture exposure can vary by material and coating.

Are these mounts easy to install, or do I need a professional?

Installation typically involves bolting the wrap or mount to the existing frame holes and securing the air tank within the bracket. Many truck owners handle this themselves with basic hand tools, but if your setup requires drilling new holes or if you're replacing a damaged section of the frame mount, having a qualified technician install it is recommended to ensure the air tank is secured correctly and safely.

Do these air tank mounts affect DOT compliance or safety inspections?

Since air tanks are part of your truck's air brake system, how they're mounted can be reviewed during a DOT inspection. A loose, cracked, or improperly secured mount can result in a violation. Using a properly fitted, sturdy wrap or mount and confirming all hardware is torqued to spec helps keep your air brake system secure and inspection-ready.
