PVC pressure crosses are PVC-U fittings with four solvent-weld sockets. They join four lengths of matching PVC pressure pipe to create a four-way junction, with the connections arranged at 90° to one another.
Each socket fits over PVC pressure pipe of the same nominal size and is joined using PVC priming fluid and pressure-rated solvent cement. PVC pressure pipe sizes are nominal, so the stated size is different from the measured pipe outside diameter. This joining method is known as a solvent weld joint, or SWJ.
These crosses are suited to residential, commercial and agricultural irrigation, garden and landscape watering, domestic and rural water supply, sprinkler installations, pump systems, general water transfer and compatible PVC pressure pipework where a four-way connection is required.
