Find replacement air brake compressors for heavy-duty trucks, commercial vehicles, and selected diesel-powered equipment at Fab Heavy Parts. This collection includes air brake compressors for specified Cummins, Volvo, Caterpillar, Mercedes-Benz, Detroit Diesel, Deutz, and other engine or vehicle applications, along with selected compressor replacement components.

Air Brake Compressors for Trucks and Diesel Engines

An air brake compressor supplies compressed air to the vehicle's air brake system. When replacing a compressor, matching the original unit's configuration is essential for proper installation and system operation.

Our air brake compressor collection includes compressors listed for several engine and vehicle applications, such as:

  • Cummins: 6BT, 6CT, ISX, and selected ISB applications.

  • Volvo: FH12, FM12, FM16, and other specified truck models.

  • Caterpillar: 3306 and 3406 engine applications, including selected wheel loaders.

  • Mercedes-Benz: Selected OM457 engine applications.

  • Detroit Diesel: Selected Series 60 engine applications.

  • Deutz: Selected 1013-series applications.

These are examples from individual air brake compressor listings, not universal compatibility claims. Check the specific compressor's part number and application information before purchasing.

Replacement Compressors and Related Components

The collection primarily contains complete air brake compressor units, but it also includes selected compressor components, such as replacement cylinder heads and repair kits.

A complete compressor and a compressor cylinder head are different replacement options. If only part of the original assembly requires attention, review the product description to determine whether a listed component is suitable for the intended repair.

Choosing the Correct Air Brake Compressor

Before ordering, compare the original compressor's part number with the references in our replacement air brake compressor listing. Confirm the engine or vehicle model, compressor mounting arrangement, drive configuration, and air and lubrication connections using the applicable product information.

Compressors listed for similar engines or truck models may have different configurations. Do not assume they are interchangeable based on appearance or engine family alone.

If the original part number is missing or difficult to read, gather the vehicle or engine identification details and photos of the existing compressor before requesting assistance.

Because air brake systems are safety-critical, compressor installation and system testing should follow the vehicle or equipment manufacturer's service procedures.

Frequently Asked Questions

How do I find the right air brake compressor for my truck or engine?

Start with the part number on your original compressor and compare it with the replacement air brake compressor listing. You should also check your vehicle model, engine identification, mounting arrangement, and connection layout. A matching engine model alone does not always confirm compatibility. If you're unsure, send us the available identification details and photos of your existing compressor for further review.

Can I replace my air brake compressor with one that has a different part number?

A different part number may be acceptable only when the replacement is confirmed for your exact application. Compare the original and replacement references, compressor configuration, mounting points, and connections. Do not assume two compressors are interchangeable simply because they look similar or are listed for the same engine family.

Do I need a complete air brake compressor or just a replacement cylinder head?

That depends on which part of the compressor is damaged and the condition of the remaining components. Our collection includes complete compressors and selected compressor cylinder heads and repair components. A replacement cylinder head will not address every possible compressor fault. Have the compressor inspected and confirm the required repair before choosing a replacement component.

What should I do if the replacement air brake compressor looks different from my original one?

Do not install it until the differences have been checked. Compare the identification numbers, mounting points, drive arrangement, and connection locations. Some visual differences may reflect different compressor configurations rather than interchangeable designs. You can provide photos of both units and their identification markings for additional compatibility review.

What should I check before installing my replacement air brake compressor?

Check that the replacement matches the required part number and configuration, and inspect it for shipping damage. The associated air lines, fittings, and other relevant system components should also be evaluated according to the manufacturer's service instructions. Because the compressor is part of a safety-critical braking system, installation and functional testing should be performed by a qualified technician using the correct vehicle-specific procedures.
