Industrial Rubber, Inc.'s Test Tables are designed and built to hold any combination of up to 5 sizes of test plugs. IRI test plugs are available in ACME thread configurations for easy connection to IRI Quick Coupling wing halves, as well as in standard 8RD or BTC casing threads. The test plugs are quickly and easily changed out by means of a six-bolt lug pattern. IRI Test Tables come fully assembled with 1/2" XH NPT plumbing for easy drainage and pressure relief after the completion of testing. Test table and test plugs are sold separately.
