Overview

Ensure the integrity of your heavy-duty brake and suspension air systems with the Mack Volvo Air System Check Valve by Norgren. As an Original Equipment (OE) component, this valve is the gold standard for maintaining one-way air flow, preventing backflow that can lead to system failure or pressure loss. Whether you are troubleshooting an air leak on the driver side or the passenger side of the chassis, this valve provides the precision sealing required for modern pneumatic systems.

Original Equipment Reliability: The Mack Volvo Air System Check Valve Advantage

The Mack Volvo Air System Check Valve (Automann Part # 170.V20999392) is engineered for high-performance Mack and Volvo trucks. It features a metric M22 x 1.5 thread on one end and a convenient 1/2-inch PLC (Push-to-Connect) fitting on the other, allowing for rapid, tool-free line connections. Note: Because this is a genuine Norgren OE product, you are getting the same durability and safety specifications that were installed on the assembly line, ensuring your compressor doesn't overwork due to back-pressure leaks.

As we continue to build the largest inventory of commercial truck parts in Illinois, we prioritize OE-grade components that keep your fleet DOT-compliant. This Mack Volvo Air System Check Valve is a direct professional-grade replacement for Mack/Volvo 20999392. Built to survive extreme temperatures and oily environments, it is the reliable choice for air tank manifolds and suspension leveling systems.
