Cross, Slip x Slip x Slip x Slip PVC Schedule 40 4" (420-040)
$20.00
The 420-040 is a 4" PVC Schedule 40 cross fitting with four slip (socket) ports, all accepting standard solvent cement welding per ASTM D2564. The uniform 4" diameter across all four ports creates a full-size, four-way inline junction — connecting a straight-through run with perpendicular branch outlets on both sides in a single compact fitting.
Manufactured from rigid PVC compound conforming to ASTM D1784 cell classification requirements, this cross fitting delivers the corrosion resistance, chemical compatibility, and long service life that Schedule 40 PVC is known for across a wide range of commercial, industrial, and municipal piping applications. The Schedule 40 wall thickness provides reliable pressure-rated performance for both pressurized distribution systems and gravity-flow installations.
The 420-040 is a foundational fitting for grid-style distribution networks where a single mainline must branch simultaneously in two perpendicular directions at full diameter — a layout common in fire suppression systems, large-scale irrigation grids, industrial process loops, and municipal water distribution. The all-slip configuration produces four permanent solvent-welded joints, making it the appropriate choice where long-term leak-free performance is the priority and connections will not require future disassembly.
