BREATHER PLUGS

Breather plugs are essential components designed to ensure ventilation and pressure balancing within tanks and closed systems, preventing the buildup of pressure or vacuum that could compromise functionality. Primarily used in oil-immersed devices such as gearboxes, mechanical transmissions, axles, and hydraulic power units, vent plugs control oil pressure inside, preventing issues related to overpressure.

Thanks to their versatility, vent plugs are used in a wide range of sectors, including automotive, manufacturing, and agriculture.
