Repair leaking fittings instantly with the new Fitting Savers! Also known as the Frankenplug™. Designed to provide a long term repair to broken, cracked or poorly glued fittings. Remove eyeball and insert the Fitting Saver into the broken fitting. Tighten the hex nut to expand the rubber collar which seals inside the pipe and at the wall fitting. Once installed a cosmetic face plate hides the rubber seal and nut. Water flow through 3/4" diameter opening bypasses the damaged area when the pool's circulatory system is put back into service.
