Equal Tee Configuration
The Lined Equal Tee joins three pipe runs of equal diameter at a single point, with a 90° branch off the main run. It’s the standard tee for distribution headers, process loops, and any branching point where flow splits roughly evenly between the run and the branch.
Investment cast bodies are lined throughout with uniform thickness in all three legs — including the inside corner where the branch meets the main, where transfer-molded linings often thin out.
Flange dimensions match standard Lined Pipe and Lined Elbow specifications, so the equal tee drops directly into existing lined pipelines without adapter flanges.
