Abstract
A plastic oil filter assembly comprises a closure plate having a plurality of radial supporting fins disposed on the inside surface thereof, a filter member having a saw-toothed coupling for tightly engaging with the plurality of radial supporting fins of the closure plate through a multiple-slit rubber valve, and a transparent exterior enclosure. The plastic oil filter assembly is simple in construction, inexpensive to manufacture, durable in use, and permits easy checking of the contamination level in filters of the filter member. The plastic oil filter assembly can reduce waste by permitting recycling of the used plastic filter assembly as a raw material.
