PVC pressure barrel union couplings are PVC-U fittings with a solvent-weld socket at both ends and a removable centre union connection. They join two lengths of matching PVC pressure pipe in a straight line while allowing the pipeline to be disconnected and reconnected without cutting the pipe.
Each socket fits over PVC pressure pipe of the same nominal size and is joined using PVC priming fluid and pressure-rated solvent cement. The centre union can then be assembled or disassembled when access to the pipeline, equipment or connected components is required.
PVC pressure pipe sizes are nominal, so the stated size is different from the measured pipe outside diameter. Confirm the correct nominal pipe size before ordering.
These barrel union couplings are suited to residential, commercial and agricultural irrigation, garden and landscape watering, domestic and rural water supply, pump systems, filters, pool and spa equipment, general water transfer and compatible PVC pressure pipework where a removable connection is useful.
