Prevent Costly Leaks with Captain O-Ring's 2-Pack Replacement O-Rings for SunSun Canister Filters

Ensure your aquarium's canister filter is functioning properly by fixing any leaks with Captain O-Ring's replacement o-rings. Keep a spare on hand to be prepared for future issues and avoid costly water damage.

These o-rings are compatible with SunSun HW303A (HW-303A, 303A) and HW303B (HW-303B, 303B) aquarium canister filters. Before purchasing, confirm your model matches one of the above to ensure you order the correct size that fits your filter.

The o-rings provided are an exact match in size, tolerance, and material to the original ones that came with your canister filter. Molded from OEM spec synthetic rubber, they are built for long-lasting performance and durability.

Proudly assembled in the USA, these replacement lid/cover/head seal o-rings are manufactured and warrantied by Captain O-Ring LLC.

Approximate O-Ring Dimensions: - Inside Diameter: 8.70" (just under 8-3/4") - Outside Diameter: 9.12" (about 9-1/8") - Thickness: 0.215" (between 3/16" and 1/4")

The package includes two (2) o-rings, also referred to as gaskets, seal rings, or rubber rings. Replace your old, worn, and leaking o-ring, and keep the spare on hand for the future with this convenient 2-pack.
