HaywardSPX0714L Cover O-ring Replacement for Hayward Multiport Valves and Sand Filter Systems

does the sp0714t variflow top mounted multiport valve come with the o-ring that fits between the valve and the sand filter tank

I have ordered an o-ring for my s270t hayward sand filter value, 3 times i ordered and 3 times i received the wrong size. does anybody know what they?

Will this fit model spo714g11?

Fit vari-flow valve sp 711-13 to tank seal? not inside valve but valve to tank where tank to valve conection accomplished with a clamp and no threads
