The lid clamping nut is an essential structural element of the SMG filter tank that holds the lid firmly closed even under higher water working pressure. A loose or damaged nut causes water leaks and a pressure drop in the filtration system.
The part is made of high-strength polyamide resistant to chlorinated water and mechanical stress. The thread is precisely manufactured for direct compatibility with the lid and body of the SMG tank.
Replacement is quick and does not require specialized tools. We recommend checking the nut at every seasonal start-up and replacing it immediately if it shows cracks, deformation, or a worn thread.
