Cross, Slip PVC Schedule 80 1-1/2" x 1" (820-211)

The 1-1/2" x 1" PVC Schedule 80 Reducing Cross (Part No. 820-211) 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 step down meaningfully from 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 reducing cross configuration, the two opposing run ports maintain the larger 1-1/2" diameter while the two opposing branch ports reduce to 1". The half-inch step-down from run to branch is more pronounced than in the adjacent 820-212 (1-1/2" × 1-1/4"), making the 820-211 the appropriate selection where branch circuits carry noticeably lower flow requirements than the main run — such as instrumentation feeds, chemical injection laterals, sampling lines, or secondary distribution circuits that must be tapped simultaneously at a single junction point off a 1-1/2" main.

As with all cross fittings, the four-way geometry is the defining advantage over a tee. Where a tee delivers one branch off a run, a cross delivers two opposing branches at the same location — consolidating what would otherwise require two separate tees and an intervening pipe spool into a single fitting, reducing joint count, assembly complexity, and overall installed length in compact mechanical spaces.

The 1-1/2" × 1" combination appears frequently in chemical distribution skids, instrumentation manifolds, compact process loops, and small-bore mechanical assemblies where the run-to-branch reduction reflects deliberate flow partitioning — directing the majority of flow through the 1-1/2" run while simultaneously supplying two 1" branch circuits from a single junction point.

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.
