GripTight

GripTight™ High Pressure Test Plug

 (153)
I.D. sealing test plug for high pressure hydrostatic testing of pipe, pipelines and pressure vessels.

Note: Never use a test pressure greater than the weakest component in the system can handle. Test Pressure specified in table is equivalent to 80% of the pressure that will yield ASTM A106 Grade B pipe. The test pressure for higher and lower strength pipes will differ proportionally. The maximum test pressure for higher strength pipe must never exceed the highest test pressure listed for that pipe O.D.

Specifications subject to change without notice.
