Ring 151.37.184A is an oil-resistant sealing ring used as part of the new filter 151.37.014-1A installed in the gearboxes of HTZ tractors.
The filter design uses two such rings, which are located above and below the filter element 761-00-00-00, pressing tightly against the filter pipe 151.37.015-3. Their main task is to prevent oil from bypassing the filter element by directing the flow through the filter paper, which ensures effective oil cleaning.
The rings are made of special wear-resistant and oil-resistant rubber, resistant to high temperatures and the aggressive environment of transmission oils.
They are used on tractors T-150, T-151, T-156, HTZ-17221 and other models where filters of the appropriate type are installed.
