Oil level sight glasses for visual monitoring of level: The oil level sight glass is a fitting for level indication of liquids. Our oil level sight glasses are made of lightweight metal with a hexagonal body. The sight glass is made of natural glass. The oil level sight glasses are heat-resistant up to 100 °C. Filler necks for filling of oil tank: Filler necks with filler breathers are intended for filling or re-filling of oil 油箱. The integrated filler breather filters the air that flows back into the tank so that no dirt from outside is penetrating (filter quality 10 µm).
