These self-adhesive flange covers protect the full face of the flange and sealing surface. The protective back is easily peeled off so these covers can be quickly and easily installed. The adhesive is specially formulated to not leave any residue on the flange upon removal. Additional shapes and sizes are available. Sizes listed are in accordance with ANSI B-16.5 and ANSI B-16.47, but can be made to fit a wide range of virtually any flange.
