GRIPTIGHT® High Pressure Test Plug

The safe way to pressure test open-end pipe and tubing
High pressure pipe testing is safer than ever before, thanks to EST Group’s GripTight high pressure test plug. Unlike other plugs that can loosen and eject under high pressure, the GripTight high pressure test plug actually uses test pressure to grip and seal more securely against the pipe’s inner diameter. The greater the pressure, the greater the grip!

The result is a quicker installation, better sealing, and all around safer testing. Operating pressures to 14,000 PsiG (960 BarG). Sizes from 1/2” to 24” (11.9mm to 596.1mm). Larger sizes 26” through 42” (660.4mm to 1066.8mm) available on request.

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.

Positioning washer:

Prevents plug loss in pipe end.

Retaining spring:

Ensures retraction of gripper segments. Superior to O-ring design.

Vent Caps:

Newly designed vent caps provide an efficient and quick method for venting air out of the piping system and filling the test pipe with test medium.

Easy to maintain:

Replacement seals and grippers readily available and easy to replace.

Super stock:

1/2” to 24” in schedule 40 and 80 (DN25 to DN200) sizes are usually in stock for same or next day shipment.

Optional seals:

Flouroelastomer (Viton®* or equivalent), Silicone, EPDM, Neoprene
