Breather Plug, 1/4"

Breather Plug, 1/4"

The 9-4195-4 Breather Plug is a compact venting component designed to equalize pressure and allow airflow in sealed housings, reservoirs, and gear cases. Installed in a 1/4" threaded port, this breather plug helps prevent pressure buildup while allowing internal components to breathe, reducing the risk of seal damage or fluid leaks. Small but important, it plays a key role in maintaining proper operation of enclosed mechanical systems—because even machines appreciate a little fresh air now and then.
