PVC pressure end caps are PVC-U fittings with a solvent-weld socket used to stop or blank the end of PVC pressure pipe. They are commonly used to close unused pipework, finish the end of an installation or isolate a section of pipe.
The cap 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 caps are suited to residential, commercial and agricultural irrigation, garden and landscape watering, domestic and rural water supply, pump systems, pool and spa equipment, general water transfer and compatible PVC pressure pipework.
