Genuine BioPro / Hopar / PetWorx Canister Filter Head O-Ring Replacement Seal (800 / 1200 Models)

Prevent or fix frustrating aquarium leaks with this genuine factory-spec replacement main canister head O-ring. Over time, original filter seals face constant compression, temperature shifts, and routine maintenance handling, which eventually causes the rubber to stretch, dry out, or crack. A compromised seal drops your water pressure and risks catastrophic floor flooding.

This premium, high-density nitrile rubber O-ring is engineered specifically for the motor pump heads of 800 L/H and 1200 L/H canister units across major reliable trade brands like BioPro, Hopar, PetWorx, and Bioscape. It forms an immediate, completely airtight and watertight barrier between the power head and the canister body container. Replacing this seal annually ensures your high-performance filtration loop retains peak pressure, keeping your aquarium water clear and operating at near-silent decibel levels.
