The Duplex Oil Filter Valve Decal Film includes a prominent arrow or indicator showing the direction of oil flow through the duplex valve. This arrow points from the oil inlet (where oil enters the filter system) to the oil outlet (where filtered oil exits the system). It also consists of information that clarifies where fresh, unfiltered oil should enter the system and where filtered oil should exit. In addition to the flow direction, the decal includes information about the proper direction for filling the engine with oil after maintenance or an oil change. This helps prevent airlocks or improper oil circulation. This is crucial for maintenance and ensuring continuous filtration.Attributes:• Resistance to fading of stickers and lettering when exposed to extreme working temperatures• Resistance to leaving remains of adhesive on paint when removed• Ease of adhesion• Accurate and precise graphic printApplications:This Duplex Oil Filter Valve Decal Film helps technicians and operators correctly understand how to install and maintain the duplex oil filter system.
