Abstract: A pipe testing fixture including a housing with a chamber, an aperture centrally disposed on the housing. A groove centrally disposed within the lower chamber. A pipe fluidly engages the chamber through the housing. A pipe closure body with a handle slidingly engages the aperture and chamber with a plate disposed on the handle. The plate slidingly engages the chamber, the lower end sealingly engaging the groove, configured to seal the lower chamber of the pipe. A plate face gasket continuously disposed on the front and rear sides of the plate. A locking pin is engagable through a pin hole upon positioning the pin hole outside the upper chamber. The engagement and alternate disengagement of the locking pin through the pin hole places the plate in an open locked position and an alternate closed position within the chamber. A separate carrier pipe segment engages the pipe portions.
