Cross, Slip PVC Schedule 80 1-1/2" x 3/4" (820-210)

The 1-1/2" x 3/4" PVC Schedule 80 Reducing Cross (Part No. 820-210) is a pressure-rated, gray-body fitting designed to create a four-way junction in a Schedule 80 PVC piping system where the branch ports carry a substantially reduced diameter relative to the main run. All four ports accept solvent-cement joints in a slip (socket) configuration, producing a rigid, leak-resistant assembly suited to the elevated pressures and chemically demanding environments where Schedule 80 is specified.

In this configuration, the two opposing run ports maintain the full 1-1/2" diameter while the two opposing branch ports reduce to 3/4" — a three-quarter-inch step-down that represents the most significant run-to-branch reduction in the 1-1/2" reducing cross series. This pronounced reduction makes the 820-210 the appropriate selection where branch circuits serve low-flow purposes relative to the main run: chemical injection ports, instrumentation supply lines, pressure gauge feeds, small-bore sampling connections, or secondary service taps that must be introduced simultaneously at a single four-way junction point off a 1-1/2" pressure main.

The cross fitting's fundamental advantage over a tee remains the same at this size — two opposing branches delivered at one location, consolidating what would otherwise require two tees and a pipe spool between them into a single fitting with fewer solvent-cement joints, a more compact footprint, and reduced potential leak points in the assembly. In the 1-1/2" × 3/4" configuration specifically, this advantage is most apparent in instrumentation panels, chemical dosing skids, and compact process assemblies where the 3/4" branch size reflects a deliberate design decision to supply small-bore service circuits off a larger-diameter main without additional reducing hardware downstream.

Manufactured from Type I, Grade I PVC compound, this fitting conforms to ASTM D2467 dimensional standards and provides the increased wall thickness and pressure ratings that distinguish Schedule 80 from Schedule 40. Compatible with Schedule 80 PVC pipe and solvent cements conforming to ASTM D2564.
