Description
The Midland Haldex 90554078 is a low-pressure inline check valve designed for air suspension and brake system plumbing. Both ports are 1/8″ NPT, and the valve opens at approximately 2-4 PSI, allowing airflow in one direction only. Installed in the supply line of a height control valve, this fitting prevents air suspension back feed if system pressure is lost, protecting the integrity of the suspension circuit. It is sold individually. Call us to confirm proper fit for your application.
