GripTight® Pipe Isolation Plug

Isolate, Monitor Upstream Pressure, and Test Flange Weld Connections with One Simple to Use Tool.

Put an end to the time-consuming conventional practice of filling and draining entire lines to test flange-to-pipe weld connections!

EST Group’s GripTight® Isolation Plug allows you to isolate and monitor potentially explosive vapors during hot work, then hydro-test new weld connections.

Integrating the functionality of a conventional Double Block and Bleed Plug with our GripTight gripper technology, GripTight Isolation Plugs provide increased operational safety by minimizing the risk of accidental blowouts/expulsions unexpected upstream pressure.

Its dual-port design creates a positive pressure barrier between the seals - safely isolating hot work from any residual upstream gases.
