Review on Optimized Marinco 30 Amp & 50 Amp Sealing Rings by Melvin Man

PERFECT replacement for a cracked threaded ring. Nothing but a flathead screwdriver to press the FLANGE of the female connector onto my 30 amp cable. The ring was placed on the flange in the same way as when mounting the tire. Simply loop it around the flange and push your thumb along the rim until it slips over the flange on the stopper. The flange will "flex" enough to allow for this. DO NOT work the ring directly with a screwdriver, otherwise it may tear again. Use the screwdriver on the FLANGE to start the process. Very easy.
