The ASC Engineered Solutions 390018083 is a Gruvlok grooved painted reducing tee designed for use in grooved piping systems requiring a branch reduction. This fitting transitions from a 6-inch main run to a 3-inch branch outlet and is manufactured from ductile iron for reliable mechanical performance under pressure. The exterior painted finish provides a layer of corrosion resistance during storage and installation. Weighing 21.06 pounds, this is a substantial fitting intended for professional mechanical piping installations. Licensed pipefitters and mechanical contractors are the primary installers.
This reducing tee is suited for commercial and industrial grooved piping installations where flow distribution or branch takeoffs are required. The grooved end connections are compatible with standard grooved couplings and fittings used in fire protection, HVAC hydronic, and general mechanical piping systems. The 6-inch by 3-inch size makes it appropriate for main distribution headers stepping down to smaller branch lines.
Designed as an OEM-style grooved reducing tee for use with standard grooved pipe coupling systems in commercial and industrial mechanical piping installations.
Installation should be performed by a licensed pipefitter or mechanical contractor in accordance with applicable mechanical codes. Depressurize and drain the piping system fully before cutting in or replacing any grooved fittings. Ensure grooved pipe ends are clean, properly dimensioned, and free of burrs before seating couplings. Verify gasket selection and coupling torque requirements per the coupling manufacturer's published specifications.
