ELESA Breather Cap Outer Diameter 31mm Thickness 29.5 BM-1/2 1 pc

Catalog number: BM-1/2 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 drastically. ●The special internal inclined blades protect against oil splashes, so there is no oil leakage under normal conditions of use. In addition, the air filter is built into the ventilation hole, so there is no need to worry about environmental pollution due to oil fumes.
