Review on 🐠 Enhance Your Canister Filter Performance with Marineland PR11942 Aquarium O Ring Gasket Replacement Kit for Model C360 by Michael Woods

This o-ring kit does not contain all the o-rings required for the Marineland C-360. This kit contains only 2 small valve block o-rings that require 4. The 2 included in the kit are slightly larger so I can't fully seat or lock the valve block. I had to reset the old ones. The large o-ring on the canister lid fitted, but made the lid tight enough to put back on. I bought this kit because my pump was sucking air and the cap o-ring seemed to fix that problem, so at $12 I'm biting my teeth and not returning it. I would not recommend this product as smaller o-rings will not fit.
