• Line endsFor securely closing the end of a flanged pipe.
• Pressure testingIndispensable item for pressurising a section of the network and verifying its watertightness.
• Equipment isolationAllows the connection to a pump or tank to be "blanked off" for safe maintenance work.
• ManholesUsed as a blind cover on tanks and reactors.
• Future extension pointsFor sealing a tee branch that will be used in a future extension of the network.
