These o-rings did not fit my standard 10" filter housings. My housings have the small groove on the inside below the threads for the o-ring and these are approx 1/4 inch too small, much too small to even stretch into the groove.

They were supposed to be three and a half inches they turned out to be that believe 3 in they were marked wrong it wasn't Amazon's fault I think they just put them in the wrong bag at the factory but I couldn't use them I sent it back it was a great price 10 of them for the money
