  • Method and apparatus for reinforcing a tubular-shaped sealing collar extending from a filter apparatus
    Patent number: 8424686
    Abstract: A method and apparatus for reinforcing a tubular-shaped sealing collar, extending from a filter cartridge are provided, by embedding, or substantially encapsulating, a reinforcement element within the tubular-shaped sealing collar, for resisting a change in circumference of at least a portion of the tubular-shaped collar. The collar may be formed from a resiliently compressible foam material, and the reinforcement element may be formed from a substantially non-compressible material.
