A test apparatus for testing the fluid tightness of pipes of different sizes includes a one-piece main body having a tubular portion defining a chamber with an internally threaded wall portion that can be screwed separately onto an externally threaded pipe in a fluid-tight manner. The one-piece main body has a head portion connected with the tubular portion. The head portion has a gauge port in fluid communication with the chamber. The head portion has a test fluid inlet port in fluid communication with the chamber and the gauge port. The gauge port has the same configuration as the test fluid inlet port whereby a test gauge can be connected in either the gauge port or the test fluid inlet port and a test fluid supply line can be the connected in either the test fluid inlet port or the gauge port.
