ABSTRACT:
A core extender and seal are provided which may be used in combination with cartridge filters. The core extender includes a body having first and second ends which are connected by longitudinal communication means through the core extender body. A radially extending shoulder extends from the body and is axially spaced from at least one end of the body, and preferably is a flange having on at least one lateral surface thereof an annular sealing ring. An external surface extends from at least one end to the radially extending shoulder. The portion of the body defined by an external surface may be inserted into the longitudinal bore of the filter cartridge in order to perform a sealing and connecting function between adjacent filters or a cartridge filter and the filter housing. Adjacent cartridge filters may be connected and adjacent radial surfaces sealed from filtrate leakage by placing an annular sealing ring therebetween such that the peripheral edge of the ring is pressed into the end surface of each cartridge filter. The annular sealing ring has an inside diameter which is greater than the diameter of the bore of the cartridge filter while the outside diameter of the annular ring is less than the diameter of the cartridge filter. The annular sealing ring has a peripheral edge which is capable of being pressed into an end surface of a cartridge filter in order to seal adjacent radial surfaces of two cartridge filters.
