High pressure pipe testing is safer than ever before, thanks to EST Group's GripTight® Test Plugs. Unlike other pipe testing plugs that can loosen and eject under high pressure - even becoming dangerous projectiles - the GripTight Test Plugs actually use test pressure to seal more securely against the pipe's inner diameter. The greater the pressure - the greater the grip! The result is safer installation, better sealing and all around safer testing.



Features & Benefits

  • Safe: Pressure on plug squeezes grippers tighter; plug can not be ejected under pressure when properly installed
  • High Pressure Performance: Have been used for pipe burst tests in a manufacturing environment. Tests at higher pressure with greater safety, typically to 80% of yield
  • Eliminates Weld Caps: No welding or cutting required. Speeds fabrication testing, reducing test times up to 80%
  • Engineered Seal Design: Reduces seal wear for long lasting performance
  • Optional High Pressure Pipe Cap: Plugs can be used in solid or ported configurations
  • Positioning Washer: Prevents plug loss in pipe end, and eliminates plug lock-up after hydro test, common with inferior plug designs
  • Retaining Spring: Assures retraction of gripper segments. Superior to O-ring design
  • Easy to Maintain: Replacement seals and grippers readily available and easy to replace
  • Optional Seals: Viton®, Silicone, EPDM
