Bullhead Tee, Slip x Slip x Slip PVC Schedule 40 3" x 3" x 6" (401-344)

The 3" x 3" x 6" PVC Schedule 40 Bullhead Tee (Slip x Slip x Slip) is a large-differential specialty fitting designed for systems where two smaller lines must converge into a significantly larger outlet. With 3-inch slip sockets on both run ends and a 6-inch slip socket on the branch, this fitting accommodates a full pipe diameter doubling — making it one of the more pronounced bullhead configurations available in Schedule 40 PVC.

In a bullhead tee, the branch connection is intentionally oversized relative to the run connections. This distinguishes it from a standard reducing tee, where the branch is equal to or smaller than the run. The practical purpose is flow management: by providing a substantially larger branch cross-section, the fitting absorbs the combined volume of two incoming runs without the sharp velocity increase that would occur in an undersized outlet. The 3" to 6" step-up is particularly effective in gravity-flow collection systems, pump suction assemblies, and drainage manifolds where preventing back-pressure or turbulence at the convergence point is a design priority.

All three connections are slip-socket, intended for permanent solvent cement installation. The resulting joint is pressure-tight, structurally integral, and appropriate for buried, exposed, or enclosed mechanical installations. Manufactured to ASTM D2466 standards and compatible with Schedule 40 PVC pipe in both 3-inch and 6-inch sizes.

Industries & Applications:

• Pump Suction Headers — The large branch-to-run ratio makes this fitting well-suited for combining two 3" suction lines into a single 6" pump inlet, reducing inlet velocity and improving pump efficiency
• Gravity Drainage & Collection Mains — Used in drainage systems where two 3" lateral lines discharge into a 6" collection main, allowing free flow without back-pressure buildup at the junction
• Irrigation & Agricultural Systems — Incorporated at submain convergence points on large-scale irrigation infrastructure where multiple smaller laterals consolidate into a larger distribution main
• Municipal Water & Wastewater — Specified in treatment plant piping, pump station headers, and collection system manifolds requiring a controlled step-up from smaller inlet lines to a larger common outlet
• Industrial Process Piping — Suitable for chemical-resistant manifold assemblies where two 3" process lines feed a single 6" outlet in water treatment, chemical handling, or industrial fluid conveyance
• Stormwater & Site Utilities — Applied in civil utility layouts where two smaller drainage runs combine into a single larger collection main at a designed convergence point
