UltraZap cartridge filter spares are the small parts that keep a cartridge filter housing sealed and serviceable in pond, aquarium and fish tank filtration. The range covers the housing o-ring, the replacement lid and the retaining nut — the first places to look when a housing starts weeping, or when a lid is cracked or stuck. Swapping the tired part is quicker and cheaper than replacing the whole filter.

Good to know:
– Cartridge filter o-ring
– Replacement filter lid
– Housing nut
– Sold per part, so you replace only what has failed
