Hydrostatic Pressure Testing Solution for Long Radius Elbows

Reduce material and labor costs when pressure testing pipe spools and piping systems terminating in long radius elbows with EST Group’s GripTight Elbow Test Plug.

GripTight Elbow Test Plugs reduce testing time by up to 85% over conventional methods by eliminating the need to weld on and cut off end caps to perform hydrostatic pressure tests. A time consuming process that can be both expensive and labor intensive.

Our Elbow Test Plug features a patented GripTight MAX® self-aligning gripper and seal design. Working together, these features provide a safe and effective testing environment that uses test pressure to grip more securely against the pipe.  Hydrostatic pressure testing of long radius elbows has never been faster or easier!
