Astralpool ZX / Zodiac ZXC Filter Blanking Cap 50mm Black (Plain, No Drain) - 78214

Genuine Astralpool plain blanking cap, 50mm, black, part number 78214. It seals the 50mm port on the ZX-family cartridge filter tank where no drain is required. Supplied on its own. This is the plain version - if you want a cap with a screw drain for winterising or emptying, that is the 78218.

This is the same filter sold under several brands - Astralpool ZX, Hurlcon ZX, Zodiac ZXC, Zodiac ZCF / Titan ZCF, Astral SMART, Filtrite CF and Aquatight. The Zodiac ZXC is simply the Zodiac-badged Astralpool ZX.
