Easy to install and fits perfectly on my CF700 filter. The priming process is smooth now, no more air locks. Works well with my aquarium setup and has improved water flow.

Fits my CF500 without any issues. I noticed better initial water flow after installing the plug. It’s a small part but makes a big difference in filter performance.

Installed it during a filter replacement and it went in smoothly. No leaks or misalignment. My filter now primes faster and runs more efficiently.
