Abstract
An encapsulated filter cartridge assembly is disclosed which is adapted and configured for reception within an elongated cartridge housing of a filtration system. The filter cartridge assembly includes an elongated filtration element, a connector head positioned adjacent an upper end portion of the filtration element, an outer shell extending axially from the connector head and encapsulating the filtration element, and an expansion joint integrally formed in the outer shell to facilitate expansion of the outer shell within the elongated cartridge housing.

An encapsulated filter cartridge assembly adapted and configured for reception within an elongated cartridge housing of a filtration system, said filter cartridge assembly comprising:
- a) an elongated filtration medium;
- b) a connector head positioned adjacent an upper end portion of said filtration medium;
- c) an outer shell extending axially from said connector head and encapsulating said filtration medium;
- and
- d) an expansion joint monolithically formed in said outer shell to facilitate expansion of said outer shell within said elongated cartridge housing.
An encapsulated filter cartridge assembly adapted and configured for reception within an elongated cartridge housing of a filtration system, said filter cartridge assembly comprising:
- a) an elongated filtration element having opposed first and second end portions;
- b) a connector head positioned adjacent the first end portion of said filtration element;
- c) an end cap positioned adjacent the second end portion of said elongated filtration element;
- d) an outer shell extending from said connector head and encapsulating said filtration element and said end cap;
- and
- e) an expansion joint monolithically formed in said outer shell to facilitate axial expansion of said outer shell within said elongated cartridge housing.
A fluid filtration system comprising:
- a) a cartridge adapter including interlocking means for detachably engaging a cartridge housing;
- b) an elongated cartridge housing including means for cooperating with said interlocking means, said cartridge housing being adapted and configured to receive an encapsulated filter cartridge assembly;
- and
- c) an encapsulated filter cartridge assembly including:
- i) an elongated filtration element;
- ii) a connector head positioned adjacent an upper end portion of said filtration element and defining fluid flow ports configured to communicate with said cartridge adapter, said connector head configured to sealingly engage said cartridge housing;
- and
- iii) an outer shell extending axially from said connector head and encapsulating said filtration element, said outer shell having an expansion joint monolithically formed therein to facilitate expansion of said outer shell within said elongated cartridge housing.
An improved encapsulated filter cartridge assembly adapted and configured for reception within an elongated cartridge housing of a filtration system and of the type having an elongated filtration medium that operatively cooperates with a connector head that is positioned adjacent an upper portion of the filtration medium and an outer shell that extends axially from the connector head and encapsulates the filtration medium, wherein the improvement comprises an expansion joint monolithically formed in the outer shell to facilitate expansion of the outer shell within the elongated cartridge housing.
