GripTight® Isolation Plug

Monitor Upstream Pressure, Isolate & Test Weld Connections with One Tool!  


Protect your plant personnel today! 

Positively isolate and monitor potentially explosive vapors during hot work, then hydrotest new weld connections with one simple to use tool. Dual port design creates a positive pressure barrier between the seals - safely isolating the hot work from any residual upstream gases.

GripTight Isolation Plugs integrate our GripTight gripper technology and the functionality of a conventional Double Block and Bleed for increased operational safety, minimizing risk of accidental blowouts/expulsions due to unexpected upstream pressure.

Test Pressure:

  • 2250 PsiG (155 BarG) between the seals
  • Upstream pressures up to 1500 PsiG (103 BarG)

Size Range: 3/4” to 48” NPS (DN20 to DN1200) - larger sizes available upon request

Standard Seal Material: Urethane – alternative materials available upon request

Features:

  • Monitor potentially explosive vapors during hot work
  • Dual port system allows water to be circulated between seals, providing improved cooling during pre/post weld procedures
  • Gripper technology minimizes risk of accidental blowout/expulsion
  • Creates a positive pressure barrier between seals
  • Lightweight, aluminum and steel construction 
  • Perform tests with less than a gallon (3.8L) of water - reducing fill times, and waste/treatment expenses
