About the tee

An equal tee splits or combines flow at 90°, with all three outlets of the same bore. One of the most common fittings in any piping system: used for branch connections, header distribution, and flow combining.

Three outlets at 90°: two run ends and one branch
Equal bore on all three outlets (equal tee)
Full-penetration butt weld end connections per ASME B16.9
Available in all pipe schedules and material grades
Barred variant available for pig-able pipeline systems
