Bullhead Tee, Slip x Slip x Slip PVC Schedule 40 5" x 5" x 6" (401-492)

The 5" x 5" x 6" PVC Schedule 40 Bullhead Tee (Slip x Slip x Slip) is a specialty fitting designed for applications where the branch outlet is larger than the two run connections — the defining characteristic of a bullhead tee. With 5-inch slip sockets on both run ends and a 6-inch slip socket on the branch, this fitting is engineered for systems that collect or converge flow from two smaller lines into a larger main, or conversely distribute flow from a larger header into two downstream runs.

Unlike a standard reducing tee — where the branch is equal to or smaller than the run — a bullhead tee produces a flow profile that requires careful hydraulic consideration. When used as a collection point, the larger branch minimizes velocity increase as combined flow exits the fitting. This makes the bullhead configuration a practical choice in pump suction headers, gravity drainage collection mains, manifold assemblies, and irrigation submain consolidation points where managing flow volume is more critical than conserving fitting size.

All three connections are slip-socket, designed for permanent installation using PVC solvent cement. This provides a leak-free, structurally sound joint suited for buried, above-ground, and mechanical room installations. The fitting is manufactured to ASTM D2466 standards and is compatible with Schedule 40 PVC pipe.

Industries & Applications:

• Pump Suction Headers — The bullhead configuration is well-suited for combining two 5" suction lines into a single 6" inlet, reducing turbulence and velocity at the pump flange
• Irrigation & Agricultural Mainlines — Used at convergence points where two submain runs consolidate into a larger distribution main on large-acreage systems
• Industrial Process Piping — Appropriate for manifold assemblies in chemical processing or water treatment where multiple inlet streams feed a common larger outlet
• Municipal & Civil Infrastructure — Incorporated in stormwater, drainage, and utility collection systems where two lines of equal size feed a larger downstream main
• Commercial Plumbing & Mechanical — Specified in mechanical room manifolds and large building drain collection systems requiring a transition from dual smaller runs to a single larger outlet
• Aquatics & Water Features — Used in high-volume recirculation systems at commercial pools and water parks where combining return lines into a larger manifold is required
