NOV/Fiber Glass Systems (FGS) has issued an important notice to installers regarding its 2” Primary Molded Fittings.
FGS recently introduced 2” Primary Molded Fittings designed to be compatible with both Red Thread™ IIA pipe and Dualoy™ pipe. However, the bell dimension of the new fittings is larger in diameter. Under certain conditions 2” Red Thread™ IIA pipe bonded with 8000 series adhesive will insert past the end of the tapered bell in molded 45-degree and 90-degree elbows, tees and bushings, leading to poor bonds. Therefore, installers should check the settings on their tapering tools, measure the dry insertion prior to bonding, or check with the manufacturer if they are unsure about their fittings.
