Filler necks and oil level sight glasses

Oil level sight glasses for visual monitoring of level:

The oil level sight glass is a valve for level indication of liquids. Our oil level sight glasses are made of lightweight metal with a hexagon body. The sight glass is made of natural glass. The oil level sight glasses are 100 % heat resistant. 
 

Filler necks for filling of oil tank:

Filler necks with filler breathers are intended for filling or re-filling of oil tanks. 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).

Provided with a filler sieve, they furthermore ensure initial coarse filtration when filling the tank.
