Dorman 924-5830 Air Brake Reservoir

Dorman 924-5830 Air Brake Reservoir

Dorman 924-5830 is a carbon steel air brake reservoir built for air-actuated braking and suspension systems. It replaces a corroded or leaking air tank with an OE-style reservoir that matches the original port layout for straightforward service on commercial truck and bus applications.

Key Features

• Carbon steel construction with a black finish
• 24 in. length and 10 in. diameter
• 28 L tank volume with one chamber
• Maximum working pressure: 150 PSI
• Seven NPT ports: five 1/2 in. ports and two 1/4 in. ports
• Strap-on mounting type
• Part number 924-5830 for direct identification

Detailed Description

This air brake reservoir is designed to restore air storage capacity in braking and suspension systems when the original tank is rusted, leaking, or no longer holding pressure. The 924-5830 uses a single-chamber design and the same port configuration expected from the original equipment tank, helping maintain proper air routing and system function. For fleet maintenance, heavy-duty repair, and replacement on vehicles such as Freightliner and International truck platforms, Dorman 924-5830 provides a service-ready reservoir built to the listed dimensions and pressure rating.

This part cross-references Monroe Shocks & Struts (e.g., 0802348) for the same application.

What It Helps Fix

• Air loss caused by a leaking reservoir
• Reduced braking performance from corroded tank walls
• Suspension air supply issues tied to damaged storage capacity
• Pressure retention problems in air-actuated systems
• Service downtime from a failed OE-style air tank

Installation Notes and Tips

Verify tank dimensions, port count, port thread sizes, and strap-on mounting layout before installation. This reservoir does not include mounting hardware, threaded mounting brackets, or a valve. Confirm the vehicle’s air line routing and port usage against the original tank before placing the unit into service. For Freightliner and International applications, match the existing reservoir configuration to the 7-port layout shown here.

Quality Assurance

Dorman manufactures replacement components to match original equipment form and function where specified. Part number 924-5830 is built from carbon steel with a 150 PSI maximum working pressure rating and OE-style port configuration for air brake reservoir replacement service.
