Polypropylene end adapters are thermally-welded to the pure polypropylene Super Fine depth filter cartridge. The positive weld assures bypass-proof performance and structural integrity without adhesives or additives, maintaining cartridge purity. All adapters are molded of the same polypropylene as the cartridge for chemical compatibility and ease of disposal.
