It’s Time to Change the Way You Pressure Test

In order to increase productivity and help achieve project milestones, you need an effective, simple, and safe method to quickly complete pressure testing because missing the boat is not an option!

EST Group’s GripTight® Test Plugs get rid of the time consuming processes of:

  • Welding on and cutting off end caps
  • Re-beveling the pipe end 
  • Pre-heat and PWHT

Eliminating welding eliminates HAZ and frees your welders up to make revenue producing welds.

Proven Performer for Pressure Testing

GripTight MAX® Test Plugs self-gripping design uses test pressure to increase the plugs' grip on the pipe – the greater the pressure the greater the grip. Patented dual-serrated grippers* provide redundant contact points between the plug and the pipe, distributing the load and increasing pressure holding capabilities. Engineered with long lasting urethane seals. High strength steel springs secure gripper segments and won’t crack and fail like O-Rings.

GripTight® Elbow Test Plugs incorporates all the design features of the GripTight MAX Test Plug while adding patented self-aligning grippers to accommodate the curvature of a long radius elbow. A test plug designed to eliminate welding on / cutting off end caps from spools ending with an elbow.

Both plugs can be installed by onsite work crews and can be used for 50-100 tests!
