Spyder gasket SM20-2

This is the spider gasket for my pool filter diverter valve, model SM20-2. The gasket is only about $10 but in a panic this fit perfectly. NINJA FLEX filament. Maybe TPU but i doubt TPU will hold up long. Light fill, maybe 15% as the gasket has to give. The part has many numbers but 271148 seems to be a common one. The part interchanges with MANY other 2 inch diverter valves.
