Review on Assortment Automotive Mechanic Plumbing Connections by Troy Arnold

Every time I buy this o-ring kit it is too thin. Until I find one thick enough to stick out of the groove, it's too big. The picture with three shows the old o-ring in the middle and the next two sizes next to it for thickness comparison. Many sizes show how big a size needs to be before they become fatter. The thickness of the old is between the last and the rest. Again, this is not an isolated case. Every time I reach for this set I'm disappointed.
