Per the supplier: It is made out of Aluminum. It can be welded but it is anodized and will have to be properly stripped. We recommend "the flange can be riveted to an alloy skin, drill proper edge clearance in the thin skin and accept marginal clearance in the relatively thick flange."
The replacement o-ring for this will be Part # 05-02611.
If you are referring to the o-ring it measures to 2.45" but if you are referring to the outer flange that measures to 3.45".
