Cross, Slip PVC Schedule 80 1-1/2" x 1/2" (820-209)

The 1-1/2" x 1/2" PVC Schedule 80 Reducing Cross (Part No. 820-209) 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 serve a minimal-flow function relative to the main run diameter. 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 1/2" — the smallest branch size in the 1-1/2" reducing cross series and a one-inch step-down that makes this fitting highly specific in its application profile. The 820-209 is the appropriate selection where the branch circuits serve purely low-flow or instrumentation purposes: pressure gauge ports, chemical injection points, sensor supply lines, bleed connections, or sampling taps that must be introduced simultaneously at a single four-way junction point off a 1-1/2" pressure main without any meaningful contribution to downstream flow capacity.

The extreme reduction ratio — 1-1/2" run to 1/2" branch — means this fitting is rarely a general-purpose distribution component. It is instead a precision specification fitting, most commonly encountered in chemical dosing skids, instrumentation manifolds, laboratory process assemblies, and compact process panels where the 1/2" branches serve defined, low-flow auxiliary functions while the 1-1/2" run carries the primary process flow through the junction uninterrupted at full capacity.

As with all cross fittings, the four-way geometry consolidates two opposing branch connections into a single fitting, eliminating the need for two separate tees and an intervening pipe spool. In the 820-209 this efficiency argument is particularly strong — the alternative of stacking two reducing tees with 1/2" branch outlets in close proximity would add significant length and joint count to what is inherently a compact instrumentation-scale assembly.

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.
