Product Overview
A reducing tee is a pipe fitting used in piping systems to connect branches of different diameters. The branch pipe has a smaller diameter than the main pipe and can be used to split or combine the flow of fluid.
Product Description
Detailed Description
Grooved Reducing Tee A tee with three grooved ports of unequal diameters, cast as a single piece from ductile iron. Installation requires cutting the main pipeline and using three sets of grooved couplings to connect the three sections of roll-grooved steel pipe, featuring a 90° reducing branch outlet.

Compatibility
Drop-in replacement
This Junyue grooved piping component is engineered for seamless compatibility with Victaulic Style 07 and Grinnell system layouts. Verify pipe OD, groove profile, gasket compound, pressure class, and project approvals before specifying as a replacement.
Technical FAQ
Application limits
- Can it be used for steam above 150 C?
- No. Do not use for steam above 150 C unless a written project-specific approval, rated gasket, and compatible body material are confirmed.
- Can it replace any grooved fitting without checking pipe OD?
- No. Pipe OD, groove standard, working pressure, gasket material, and certification scope must be matched.
- Is it suitable for potable water by default?
- No. Potable water use requires confirmation of coating, gasket compound, local sanitary approval, and project compliance.
- Can it be used in corrosive chemical service?
- Not by default. Chemical compatibility must be verified against the medium, concentration, temperature, and coating system.
