The Right Tool for the Right Job!

Isolate and monitor potentially explosive vapors during hot work, then effectively hydrotest the new weld connection with one tool.

Curtiss-Wright EST Group's GripTight Isolation Plug is built with a dual cavity port that creates a positive pressure barrier between the seals. This positive pressure barrier isolates hot work from residual upstream vapors to safeguard workers from potentially explosive vapors.

In addition, by integrating our proven GripTight gripper technology with the functionality of a conventional Double Block and Bleed plug, GripTight Isolation Plugs offer increased operational safety by minimizing the risk of accidental blowouts/expulsions due to unexpected upstream vapor and pressure.

• Self-gripping design creates a positive pressure barrier between seals, safely isolating hot work from upstream gases
• ​Test pressures up to 2250 PsiG (155 BarG) between the seals and monitor upstream pressure up to 1500 PsiG (103 BarG)
