If you want to improve flange-sealing reliability on your rigid metal parts, try LOCTITE® 5127.

Perfect for making gaskets for pumps, housings, axle covers, gear cases, split crankcases, and other areas where conventional gaskets are used. It can even be used to repair damaged conventional gaskets or as a coating/dressing for conventional gaskets.
