Product description

The Breather Filler Cap 3437-AA is a dual-purpose component for the hydraulic reservoirs of Snap-On and John Bean power units. It serves as a secure closure for the hydraulic oil fill port while simultaneously acting as a filtered vent to allow the reservoir to "breathe" as fluid levels fluctuate during operation. This prevents the formation of vacuum or pressure buildup within the tank, which could impede pump performance or cause reservoir damage. The integrated filter prevents airborne contaminants like dust and metallic particles from entering the hydraulic system, significantly extending the life of the pump and hydraulic fluid.
