Repair Process for SEBEF/ SEBEFM, SMARTFLEX penetration fittings . In an effort to provide a guideline in the event a repair is necessary, Nupi Americas strongly recommends the following steps. 1 . Locate the leak in the sump. Verify all possible leaks and mark them all . 2 . Remove all liquid from the sump . 3 . Apply a vacuum to the sump for 20 minutes to dry the leak point. 4 . Remove all the Petroseal Epoxy by scraping it off from the side involved by the leak. Remove the epoxy off of the fitting and the sump . 5 . Using an angle grinder, grind the Fiberglass wall for about 2" from the fitting edge and all around the penetration fitting . 6 . Using a cutting disk, penetrate the space between the fiberglass and the fitting for at least an 1 /8" . 7 . With a hand scraper or sharp tool , remove excess material from the space . 8 . Using Medium grade abrasive paper clean and rough up the brass or aluminum fitting surfaces . This will facilitate the epoxy's grip to the surfaces. 9 . Clean/ rinse everything with acetone . 10 . Re-apply the vacuum 11 . Fill the gap made as per step #6 with new Petroseal . Spread the epoxy over the whole metal surfaces allowing about 1 /8" thickness of epoxy to cure over it as well as the fiberglass area previously ground. 12 . Continue to vacuum for 10 minutes after application. The liquid epoxy will be forced to move into the gap that caused the leak . The excess epoxy will prevent the fitting surfaces from chemical attack. 13. After a 1 hour curing time , apply a second epoxy coat to thicken up the fitting protective layer. Prepare and perform the sump test after at least 4 hours. 14 . After testing , remove Nupi test port to assure communication between the sump and fitting .
