The Magnaloy FB Filler Breathers with Dipsticks combine reservoir ventilation and fluid level monitoring in one convenient component. Featuring a breather cap with a built-in dipstick, these units allow hydraulic systems to "breathe" by regulating air exchange while preventing contaminants like dust and moisture from entering the fluid. The integrated dipstick provides a quick and easy way to check fluid levels, ensuring the system has the right amount of clean hydraulic fluid for optimal performance and longevity. Similar to checking engine oil in a car, this design helps operators maintain system efficiency, prevent damage, and reduce downtime.
