Outperforming Six Decades of Traditional Plug Design
Years of in-house research, engineering, and testing went into GripSafe® ST before it reached the field. The result is positioned to become the new industry standard.
Independently Actuating Wedge System
Each wedge moves on its own, so load spreads evenly and every wedge keeps full contact with the pipe wall.
Gritlock® Surface Technology
An exclusive surface coating with thousands of microscopic contact points gives a secure grip without serrated teeth.
Tri-Ply® Seals
Multi-durometer seal technology, protected by patent, that resists deformation and edge mushrooming.
Lighter Body
Models 10" and larger are built from aviation-grade aluminum and stainless steel. On average, they're lighter than competing plugs.
What Crews Say
"GripSafe plugs have been valuable assets on the LNGC site. The quick and easy installation, use, and removal of the plugs have made testing plain end pipe simple. The Lifting Device makes rigging of the larger plugs into position fast, convenient, and safe. The design of the grippers leave little to no marks inside the pipe. Torque values and plug info on the front plate makes plug identification and double-checking for the right plug usage easy. Overall, the GripSafe plugs are an excellent product."
