Ventilator for Hydraulic Reservoirs
The Buyers HBF12 breather cap fits a 3/4 NPT opening on hydraulic tanks and reservoirs. It allows clean air to enter while keeping contaminants out of the fluid. The unit suits maintenance teams and machine shops that service hydraulic systems. It is designed for use with oil, chemical and coolant reservoirs.
Sustained Filtration at 40 Microns
Oil-resistant filter elements block dirt and dust particles as small as 40 microns during continuous operation. The cap maintains a free flow of air into the reservoir without clogging under normal service conditions. This steady ventilation prevents pressure build-up while protecting fluid cleanliness over long periods.
Verify Thread Size and Clearance
Confirm the tank port uses a 3/4 NPT thread before ordering. Check that the 1.625 H height and the 3 1/4 in top cap diameter fit the available space on your reservoir. Ensure the mounting location allows unrestricted airflow to the filter surface.

Questions about this item
Does the 40-micron filter element restrict airflow when the hydraulic system runs continuously?
The oil-resistant filter element is designed to provide free flow of clean air into the reservoir while trapping particles as small as 40 microns during continuous operation.
What thread size must the reservoir port have to accept this breather cap?
This breather cap requires a 3/4 NPT thread on the tank or reservoir port for proper installation.
Will the 1.625-inch height clear the filler neck on older hydraulic tanks?
The cap has an overall height of 1.625 inches, so verify the clearance above your existing filler neck before fitting it to older equipment.
