The vac port fitting is a replacement part that was made by Kreepy Krauly.
Manufactured with high-quality materials suitable for swimming pool water conditions.
This part was designed for Kreepy Krauly suction cleaners and is a threaded quick-connect adapter that is meant to connect itself to the vac port or vacuum line on your pool wall (if your pool has one, otherwise you will be using the weir) which then connects the cleaner hose. The hose is then connected to the cleaner itself giving it the sucking power which allows the cleaner to operate and clean the entirety of the surface of your pool.
This vac port fitting is white and has a spring action door making it easy to identify. Also, it was designed with a threaded base so that way it can be connected to the pool wall however, after time and use it may be a little harder to disconnect that's why we always recommend using tape when installing this part to avoid this situation, making it easy to remove.
