Pressurized filler breather cap

Pressure fill vent cap, made of chromed steel, is equipped with a 40 micron air filter and a double pressurized valve system that allows to maintain a constant pressure in the tank.
When the liquid level drops, air enters the reservoir through the suction valve and air filter. When the level rises, the pressure increase created is regulated by the safety valve (set at 0.35 Bar / 5 PSI) allowing the airflow to exit the tank only once that pressure is reached.
This pressurization system reduces the volume of air allowed in the tank, and consequently reduces the entry of impurities into the oil, keeping the fluid clean.
Ultimately, this will help the proper functioning of the hydraulic system.
These plugs are recommended for systems operating in extremely dusty environments and mobile applications where leak prevention is a must.
Base, flange mounted with 6 screws. Supplied with rubber gasket and M5 fixing screws.
Avoid contact with water.
