More Information
Summary:A one-piece filter cartridge is formed by inserting an open ended cylindrical screen and an end screen for the cylindrical screen in a mold and overmolding with engineered resinous material to form spaced annular and axial support ribs for the screen material. The cartridge is suitable for use in an hydraulic circuit for filtering bi-directional and radial flow without backwashing trapped particles from flow in one axial direction. One of the ribs has an annular groove for a seal ring for sealing about the cartridge upon insertion in a flow passage.
