ELESA Breather Cap Outer Diameter 31mm Thickness 29.5 BM-3/8G 1 pc

Catalog number: BM-3/8G Features: ●Ventilated structure allows air to flow in and out freely even with the cap attached. ●Even if a large pressure difference occurs temporarily in the tank due to a sudden rise in temperature or oil backlash, it quickly regains equilibrium with the outside air, so it is safe. Ideal for use with boosters and pressure reducers where the amount of oil increases and decreases dramatically. ●Special internal inclined blades guard against splashing oil, so there is no external leakage of oil under normal conditions of use. In addition, an air filter is built into the ventilation hole, so there is no need to worry about environmental pollution caused by oil fumes.
