GripTight MAX® Test Plug

Safe and Effective Pressure Testing

Engineered for pressure testing open-ended pipe in applications such as down hole / well-head piping, high pressure steam systems and high alloy hardened materials*. GripTight MAX Test Plugs eliminate the need to weld on / cut off end caps, allowing you to self-perform pressure tests! Cutting down on testing time and additional man hours needed for craft work.  

Patented dual serrated grippers offer additional gripping points on the pipe ID, providing the strength necessary to safely test at higher pressures. As the pressure increases the seal and grippers work together to form a leak tight seal creating a safe environment for testing.

Test Pressure: Up to 15,000 PsiG (1,034 BarG)

Size Range: 3/8” - 24” NPS (DN10 - DN600) Stock - sizes up to 48” NPS (DN1200) available upon request

Standard Seal Material: Urethane – alternative materials available upon request
