Check Valve, Air Pump, 1966-87 GM Models, 1/2"x14 Threads, 1.25" Hose Outlet

Check Valve, Air Pump, Secondary Air Injection

Air pump check valve helps prevent exhaust backflow into the secondary air injection system.

Restore proper operation of your vehicle's secondary air injection system with this air pump check valve. Designed for compatible factory emissions-control systems, this replacement valve helps maintain proper airflow direction by allowing fresh air from the air pump to enter the exhaust system while preventing hot exhaust gases from flowing backward. The secondary air injection system helps reduce harmful emissions by introducing additional oxygen into the exhaust stream, promoting the oxidation of unburned hydrocarbons and carbon monoxide. A worn or malfunctioning check valve can allow exhaust heat and gases to reach the air pump and connecting hoses, potentially damaging associated emissions components. Manufactured using quality components for dependable operation, this replacement check valve is designed to restore the one-way airflow function of the original equipment. Replacing a leaking, damaged or malfunctioning valve helps protect the secondary air injection system from exhaust backflow while supporting proper emissions-control operation. Suitable for a variety of compatible factory applications, this check valve provides a practical solution for maintaining original emissions-system functionality.
