Pipe Joint Testers

The Sealfast® Pipe Joint Tester is available in sizes from 1/2″ to 144″. The pipe joint tester is used to test a long term pipe joint prior to operation or to isolate leaks in piping systems. The pipe joint tester consists of a metal barrel (cylinder) fitted with the Sealfast® “double acting” seal rings located within recessed channels at each end.

The Pipe Joint Tester incorporates a mating flange on one end and inflatable seals beyond the joint to be tested. When the pipe joint tester is installed, the annular space between the seals becomes a fluid tight chamber, allowing the user to check the pipe joint for leakage.

Joint testers are the ideal tool for pipeline joint testing and isolation applications.
