Cross, Slip PVC Schedule 80 1-1/2" x 1-1/4" (820-212)

The 1-1/2" x 1-1/4" PVC Schedule 80 Reducing Cross (Part No. 820-212) is a pressure-rated, gray-body fitting designed to create a four-way junction in a Schedule 80 PVC piping system, with a size reduction between the run and branch ports. 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 a reducing cross, the two opposing run ports carry the larger diameter — 1-1/2" in this configuration — while the two opposing branch ports are the reduced size at 1-1/4". This arrangement allows the main flow path to be maintained at full 1-1/2" capacity while the perpendicular branches step down to 1-1/4", enabling the fitting to serve as a compact distribution or collection hub where two branch circuits of slightly reduced capacity must be introduced simultaneously at a single junction point.

The cross fitting's four-way geometry is its defining characteristic and primary advantage over a tee — where a tee provides one branch off a run, a cross provides two opposing branches at the same location, consolidating what would otherwise require two separate tees and an intervening pipe spool into a single fitting. This reduces assembly complexity, minimizes the number of solvent-cement joints in the system, and produces a more compact installation in space-constrained mechanical environments.

The 1-1/2" × 1-1/4" size combination is a common specification in instrumentation manifolds, chemical distribution panels, small-bore process loops, and compact mechanical assemblies where the slight step-down from run to branch is by design rather than coincidence — reflecting deliberate flow balancing or equipment connection sizing in the system layout.

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.
