The 420-338 is a PVC Schedule 40 reducing cross fitting with four slip (socket) connections — a 3" straight-through run and 2" branch outlets on both sides. All four ports accept solvent cement welding per ASTM D2564, creating a permanent, pressure-rated four-way junction in a single compact fitting.

Manufactured from rigid PVC compound conforming to ASTM D1784 cell classification requirements, this reducing cross delivers the corrosion resistance, chemical compatibility, and long service life that PVC is known for across demanding commercial and industrial piping environments. The Schedule 40 wall thickness provides reliable pressure-rated performance for both pressurized distribution systems and gravity-flow applications.

The four-way cross configuration makes the 420-338 well suited for distribution manifolds where a 3" mainline must simultaneously branch in two directions at a reduced 2" diameter — a layout common in irrigation headers, fire suppression grids, industrial process loops, and municipal water distribution networks. As a reducing cross rather than a standard cross, it eliminates the need for separate reducers at the branch ports, keeping the fitting count low and installation compact.

Industries & Applications:

  • Irrigation & Agriculture — Four-way header distribution where a 3" mainline splits into dual 2" zone supply lines, reducing fitting count in large-scale irrigation manifolds
  • Municipal Water Systems — Grid distribution networks and cross-feed piping at treatment facilities and pump stations requiring a compact four-way junction
  • Fire Suppression — Wet pipe sprinkler system distribution grids where cross-feed piping must reduce to branch supply lines
  • Industrial Process Piping — Four-way junctions in cooling water loops, chemical distribution, and recirculation systems requiring corrosion-resistant materials
  • Commercial Plumbing — Mechanical room distribution manifolds supplying multiple circuits from a common 3" header
  • Aquaculture & Water Treatment — Multi-tank supply manifolds where a single feed line must distribute simultaneously to branching circuits
