GripTight® Isolation Plug

Double Block & Bleed Isolation and Testing with GripTight Safety. Pipeline Isolation Plugs


Now available in a three port design!

The GripTight® Isolation Plug revolutionizes isolation and testing of pipe connections by providing unique safety features. GripTight Pipeline Isolation Plugs allow an operator to positively isolate and monitor potentially explosive vapors during “hot work”, then effectively hydrotest the new weld connection with one easy to use tool. 

The dual cavity port design allows water to be introduced to the section between the seals through the fill port while air is simultaneously evacuated through the vent port - creating an air-free barrier between the hot work and residual upstream gases.
