Test-gasket 4" 150#. Test gasket with a handle and is made out of a fibre gasket. It comes in the striking colour red. This color and the handle makes it that every one will see that there is a testgasket in the system.
For the closing off of flange connections during a turnaround or factory stop blindspades are often placed. This makes it possible to hydrotest certain parts of the system. Often ?original? expensive gaskets are used which are removed after the hydrotest. These are often spiral wound gaskets, which need some space so they can be built in between flanges. For the extra insert-gasket only a limited space is left. Thinner graphite gaskets are often used for this. A big danger is that after testing, this gasket is not exchanged by the original so that the ?temporary? gasket is no longer noticed. When restarting an installation this can lead to dangerous situations in which the ?temporary? gasket is blown out, with all its consequences.
By using our Testgasgets there is an cheap alternative. With it's handle you will see the testgasket from a distance. Our gaskets are made with a handle, which sticks out of the flange and and is manufactured in a striking red colour. This means that the gasket is always noticeable. The handle is a handy aid when assembling or disassembling the gasket. That is why our Testgaskets are easy to remove and leave no dirt on the flanges. They do not need to be cleaned again. Under normal circumstances, when hydro-testing with cold water the Testgasket can work up to pressures of 70bar.
