The ASC Engineered Solutions 390173755 is a painted grooved saddle tee fitting designed for branch connections in piping systems. Built from ductile iron with a painted exterior finish, this saddle tee connects a 6-inch main line to a 4-inch branch outlet using a grooved-end pipe joining method. At 10.11 pounds, the fitting is sized for demanding commercial and industrial applications where a reliable, leak-resistant branch connection is required. Licensed pipefitters and mechanical contractors install this type of fitting as part of grooved piping assemblies in fire suppression, HVAC hydronic, and industrial fluid systems.
This saddle tee is used in applications where a branch outlet must be added to an existing or new grooved main line without welding or threading. The 6-inch by 4-inch configuration suits medium to large-diameter piping runs in commercial mechanical rooms, industrial process piping, and fire protection systems. The grooved-out design simplifies assembly and allows for faster installation compared to flanged or threaded alternatives.
Designed as an OEM-style grooved fitting for use in standard grooved piping systems with 6-inch main pipe and 4-inch branch connections in commercial and industrial mechanical applications.
Installation should be performed by a licensed pipefitter or mechanical contractor in accordance with applicable mechanical and plumbing codes. Depressurize and drain the piping system fully before beginning work on any branch connection. Use the appropriate grooved coupling and gasket rated for the system pressure and fluid type. Follow the fitting manufacturer's assembly torque guidance and inspect all grooved joints for proper seating before returning the system to service.
