A split valve pressure test plug is provided for high pressure fluid systems to sense pressure or temperature by means of a test probe and gauge. The test probe is inserted within split valve resilient valve core members in the test plug. The split valve core members are separable and are interfitted in a male-female relationship to provide for improved sealing upon removal of the test probe. A retainer strap is further provided which retains a cap for the test plug, permits use of a wrench without interference and acts as a sealing ring in addition to a separate gasket when the cap is tightened.

A pressure test plug comprising a rigid housing having a longitudinal axis adapted to be connected through a wall from a low pressure side to a high pressure side, said housing receiving in radially compressed sealing relation a plurality of resilient valve core members arranged in tandem, each core member having a passage for a tubular probe, said passage comprising a normally closed slit, said slit removably receiving the tubular probe from the low pressure side in sealing relation, characterized in that the core members are axially moveable into and out of engagement with respect to each other and that an adjacent pair of opposed core faces have mating male and female portions engageable in sealing relation with one another to enhance said radially compressed sealing relation when the valve core members are engaged with one another, the slit in said cores passing axially through said male and female portions and removably receiving the tubular probe.
