The Hydraulic Tank Breather allows air to enter and exit the tank to equalize pressure and prevent contaminants from entering the unit. As the hydraulic system operates, the fluid heats up and expands, increasing the pressure inside the tank. The breather allows the excess pressure to escape, ensuring that the pressure remains within safe limits.Attributes:• Helps regulate pressure and maintain the cleanliness of the hydraulic fluid• Provided with a 5 PSI rating, which allows excess pressure to escape when the internal pressure exceeds this threshold.Applications:The Hydraulic Tank Breather helps maintain the proper pressure and cleanliness of the hydraulic fluid within the tank.
